Fixes for e2e tests following the Vue 3 compat upgrade (#6837)

* clock, timeConductor and appActions fixes

* Ensure realtime uses upstream context when available
Eliminate ambiguity when looking for time conductor locator

* Fix log plot e2e tests

* Fix displayLayout e2e tests

* Specify global time conductor to fix issues with duplicate selectors with independent time contexts

* a11y: ARIA for conductor and independent time conductor

* a11y: fix label collisions, specify 'Menu' in label

* Add watch mode

* fix(e2e): update appActions and tests to use a11y locators for ITC

* Don't remove the itc popup from the DOM. Just show/hide it once it's added the first time.

* test(e2e): disable one imagery test due to known bug

* Add fixme to tagging tests, issue described in 6822

* Fix locator for time conductor popups

* Improve how time bounds are set in independent time conductor.
Fix tests for flexible layout and timestrip

* Fix some tests for itc for display layouts

* Fix Inspector tabs remounting on change

* fix autoscale test and snapshot

* Fix telemetry table test

* Fix timestrip test

* e2e: move test info annotations to within test

* 6826: Fixes padStart error due to using it on a number rather than a string

* fix(e2e): update snapshots

* fix(e2e): fix restricted notebook locator

* fix(restrictedNotebook): fix issue causing sections not to update on lock

* fix(restrictedNotebook): fix issue causing snapshots to not be able to be deleted from a locked page

- Using `this.$delete(arr, index)` does not update the `length` property on the underlying target object, so it can lead to bizarre issues where your array is of length 4 but it has 3 objects in it.

* fix: replace all instances of `$delete` with `Array.splice()` or `delete`

* fix(e2e): fix grand search test

* fix(#3117): can remove item from displayLayout via tree context menu while viewing another item

* fix: remove typo 

* Wait for background image to load

* fix(#6832): timelist events can tick down

* fix: ensure that menuitems have the raw objects so emits work

* fix: assign new arrays instead of editing state in-place

* refactor(timelist): use `getClock()` instead of `clock()`

* Revert "refactor(timelist): use `getClock()` instead of `clock()`"

This reverts commit d888553112.

* refactor(timelist): use new timeAPI

* Stop ticking when the independent time context is disabled (#6833)

* Turn off the clock ticket for independent time conductor when it is disabled

* Fix linting issues

* test: update couchdb notebook test

* fix: codeQL warnings

* fix(tree-item): infinite spinner issue

- Using `indexOf()` with an object was failing due to some items in the tree being Proxy-wrapped and others not. So instead, use `findIndex()` with a predicate that compares the navigationPaths of both objects

* [Timer] Remove "refresh" call, it is not needed (#6841)

* removing an unneccessary refresh that waas causing many get requests
* lets just pretend this never happened

* fix(mct-tree): maintain reactivity of all tree items

* Hide change role button in the indicator in cases where there is only… (#6840)

Hide change role button in the indicator in cases where there is only a single role available for the current user
