Misc UI 5640 (#5762)

* Closes #5640
- Layout frame edit handle visually tweaked, no longer resizes frame contents on hover when editing.
- Gauge now centers in its container instead of left flush.
- Added large bg-icon for aggregate telemetry.
- Removed 'no class' single wrapper div in mct-tree.vue.
- Refinements to appearance of locator in save/edit overlay dialog.
- Better styling for search in progress and 'no results' messaging.
- Revised art and glyph for `icon-tabular-scrolling`.
- Change TelemetryTableType to use icon-tabular-scrolling icon and bg-icon.
- Fix bad/erroneous descriptions for Telemetry Table, LAD Table and LAD Table Set.
- Fix descriptions for multiple view types.
- Removed unused .bg-icon class.
- Fixed bad value check that was causing panes not to collapse when dragged
(by design) to a very narrow width.
- Visual style for grippy adjusted for better clarity on some monitors.
- Normalize size of alphanumeric's labels and values in Display Layouts.
- Fix margin strategy for object label in main view.
- Fixed Locator to dynamically size itself to use available vertical space.
- Added new `l-overlay-dialog` size parameter.
- Better approach to overlay sizing to make Properties dialogs larger vertically
and fullscreen overlays more apparent to the user.
- Normalized approach to numeric inputs to fix cross-browser
inconsistency with input spinners.
- Fixed layout problem in `Datetime.vue` component due to
numeric input spinners changes.
- Added object types for Display Layout drawing objects.
- Code modded in `ObjectName.vue` to grab layout object cssClass from
layoutItem.type.
- Big thanks to @jvigliotta for the assist with this!
- update snapshots
