Support binary websockets

* feat(IndicatorAPI): accept Vue components

- Adds a new property to Indicators, `component`, which is a synchronous or asynchronous Vue component.
- Adds `wrapHtmlElement` utility function to create anonymous Vue components out of `HTMLElement`s (for backwards compatibility)
- Refactors StatusIndicators.vue to use dynamic components, allowing us to dynamically render indicators (and keep it all within Vue's ecosystem).

* refactor(indicators): use dynamic Vue components instead of `mount()`

- Refactors some indicators to use Vue components directly as async components

* refactor: use Vue reactivity for timestamps in clock indicator

* fix(test): fix unit tests and remove some console logs

* test(e2e): stabilize ladSet e2e test

* test: mix in some Vue indicators in indicatorSpec

* refactor: cleanup variable names

* docs: update IndicatorAPI docs

* fix(e2e): wait for async status bar components to load before snapshot

* a11y(e2e): add aria-labels and wait for status bar to load

* test(e2e): add exact: true

* fix: initializing indicators

* fix(typo): uhhh.. how did that get there? O_o

* fix: use synchronous components for default indicators

* test: clean up, remove unnecessary `nextTick()`s

* test: remove more `nextTick()`s

* refactor: lint:fix

* fix: `on` -> `off`

* test(e2e): stabilize tabs test

* test(e2e): attempt to stabilize limit lines tests with `toHaveCount()` assertion

+## Visibility-Based Rendering in View Providers
+
+To enhance performance and resource efficiency in OpenMCT, a visibility-based rendering feature has been added. This feature is designed to defer the execution of rendering logic for views that are not currently visible. It ensures that views are only updated when they are in the viewport, similar to how modern browsers handle rendering of inactive tabs but optimized for the OpenMCT tabbed display. It also works when views are scrolled outside the viewport (e.g., in a Display Layout).
+
+### Overview
+
+The show function is responsible for the rendering of a view. An [Intersection Observer](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API) is used internally to determine whether the view is visible. This observer drives the visibility-based rendering feature, accessed via the `renderWhenVisible` function provided in the `viewOptions` parameter.
+
+### Implementing Visibility-Based Rendering
+
+The `renderWhenVisible` function is passed to the show function as part of the `viewOptions` object. This function can be used for all rendering logic that would otherwise be executed within a `requestAnimationFrame` call. When called, `renderWhenVisible` will either execute the provided function immediately (via `requestAnimationFrame`) if the view is currently visible, or defer its execution until the view becomes visible.
+
+Additionally, `renderWhenVisible` returns a boolean value indicating whether the provided function was executed immediately (`true`) or deferred (`false`).
+
+Monitoring of visibility begins after the first call to `renderWhenVisible` is made.
+
+Here’s the signature for the show function:
+
+`show(element, isEditing, viewOptions)`
+
+  * `element` (HTMLElement) - The DOM element where the view should be rendered.
+  * `isEditing` (boolean) - Indicates whether the view is in editing mode.
+  * `viewOptions` (Object) - An object with configuration options for the view, including:
+    * `renderWhenVisible` (Function) - This function wraps the `requestAnimationFrame` and only triggers the provided render logic when the view is visible in the viewport.
+
+### Example
+
+An OpenMCT view provider might implement the show function as follows:
+
+```js
+// Define your view provider
+const myViewProvider = {
+  // ... other properties and methods ...
+  show: function (element, isEditing, viewOptions) {
+    // Callback for rendering view content
+    const renderCallback = () => {
+      // Your view rendering logic goes here
+    };
+    
+    // Use the renderWhenVisible function to ensure rendering only happens when view is visible
+    const wasRenderedImmediately = viewOptions.renderWhenVisible(renderCallback);
+
+    // Optionally handle the immediate rendering return value
+    if (wasRenderedImmediately) {
+      console.debug('🪞 Rendering triggered immediately as the view is visible.');
+    } else {
+      console.debug('🛑 Rendering has been deferred until the view becomes visible.');
+    }
+  }
+};
+```
+
+
+Note that `renderWhenVisible` defers rendering while the view is not visible and caters to the latest execution call. This provides responsiveness for dynamic content while ensuring performance optimizations.
+
+Ensure your view logic is prepared to handle potentially multiple deferrals if using this API, as only the last call to renderWhenVisible will be queued for execution upon the view becoming visible.

 Open MCT (Open Mission Control Technologies) is a next-generation mission control framework for visualization of data on desktop and mobile devices. It is developed at NASA's Ames Research Center, and is being used by NASA for data analysis of spacecraft missions, as well as planning and operation of experimental rover systems. As a generalizable and open source framework, Open MCT could be used as the basis for building applications for planning, operation, and analysis of any systems producing telemetry data.

+e2e testing describes the layer at which a test is performed without prescribing the assertions which are made. Generally, when writing an e2e test, we have five choices to make on an assertion strategy:
 
 1. Functional - Verifies the functional correctness of the application. Sometimes interchanged with e2e or regression testing.
 2. Visual - Verifies the "look and feel" of the application and can only detect _undesirable changes when compared to a previous baseline_.
 3. Snapshot - Similar to Visual in that it captures the "look" of the application and can only detect _undesirable changes when compared to a previous baseline_. **Generally not preferred due to advanced setup necessary.**
+4. Accessibility - Verifies that the application meets the accessibility standards defined by the [WCAG organization](https://www.w3.org/WAI/standards-guidelines/wcag/).
+5. Performance - Verifies that application provides a performant experience. Like Snapshot testing, these tests are generally not recommended due to their difficulty in providing a consistent result.
 
 When choosing between the different testing strategies, think only about the assertion that is made at the end of the series of test steps. "I want to verify that the Timer plugin functions correctly" vs "I want to verify that the Timer plugin does not look different than originally designed".

+## Automated Accessibility (a11y) Testing
+
+Open MCT incorporates accessibility testing through two primary methods to ensure its compliance with accessibility standards:
+
+1. **Usage of Playwright's Locator Strategy**: Open MCT utilizes Playwright's locator strategy, specifically the [page.getByRole('') function](https://playwright.dev/docs/api/class-framelocator#frame-locator-get-by-role), to ensure that web elements are accessible via assistive technologies. This approach focuses on the accessibility of elements rather than full adherence to a11y guidelines, which is covered in the second method.
+
+2. **Enforcing a11y Guidelines with Playwright Axe Plugin**: To rigorously enforce a11y guideline compliance, Open MCT employs the [playwright axe plugin](https://playwright.dev/docs/accessibility-testing). This is achieved through the `scanForA11yViolations` function within the visual testing suite. This method not only benefits from the existing coverage of the visual tests but also targets specific a11y issues, such as `color-contrast` violations, which are particularly pertinent in the context of visual testing.
+
+### a11y Standards (WCAG and Section 508)
+
+Playwright axe supports a wide range of [WCAG Standards](https://playwright.dev/docs/accessibility-testing#scanning-for-wcag-violations) to test against. Open MCT is testing against the [Section 508](https://www.section508.gov/test/testing-overview/) accessibility guidelines with the intent to support higher standards over time. As of 2024, Section508 requirements now map completely to WCAG 2.0 AA. In the future, Section 508 requirements may map to WCAG 2.1 AA.
+
+### Reading an a11y test failure
+
+When an a11y test fails, the result must be interpreted in the html test report or the a11y report json artifact stored in the `/test-results/` folder. The json structure should be parsed for `"violations"` by `"id"` and identified `"target"`. Example provided for the 'color-contrast-enhanced' violation.
+
+```json
+  "violations": 
+    {
+      "id": "color-contrast-enhanced",
+      "impact": "serious",
+      "html": "<span class=\"label c-indicator__label\">0 Snapshots <button aria-label=\"Show Snapshots\">Show</button></span>",
+        "target": [
+          ".s-status-off > .label.c-indicator__label"
+        ],
+        "failureSummary": "Fix any of the following:\n  Element has insufficient color contrast of 6.51 (foreground color: #aaaaaa, background color: #262626, font size: 8.1pt (10.8px), font weight: normal). Expected contrast ratio of 7:1"

+Playwright provides 3 supported methods of debugging and authoring tests:
+- A 'watch mode' for running tests locally and debugging on the fly
+- A 'debug mode' for debugging tests and writing assertions against tests
+- A 'VSCode plugin' for debugging tests within the VSCode IDE.
+
+Generally, we encourage folks to use the watch mode and provide a script `npm run test:e2e:watch` which launches the launch mode ui and enables hot reloading on the dev server.
