Danny White 6c0439ace8 fix(ui): opaque default button hover fills (#48837)
## What kind of change does this PR introduce?

Bug fix for translucent default Button (and related control) fills that
show through stacked content on hover.

Resolves
[DEPR-636](https://linear.app/supabase/issue/DEPR-636/report-snippet-cell-expand-button-becomes-transparent-on-hover).

## What is the current behavior?

Default `Button` hover uses `bg-selection`, and dark-mode rest uses
`bg-muted`. After the colour system migration those legacy aliases point
at translucent `--accent` / `--muted`, so hover punches through whatever
sits behind the button (SQL Editor / Reports cell expand, sticky
columns, skip-to-content, etc.).

## What is the new behavior?

Default Button, Select, MultiSelect, and the CommandMenu trigger use
opaque elevation tokens (`bg-background dark:bg-card`,
`hover:bg-popover`). SkipToContent drops its opaque-plate workaround. No
global `compat.css` alias remaps.

## Additional context

- Overlay tokens (`--muted` / `--accent` / `--tertiary`) stay
intentional for washes on solid surfaces. Controls that can sit over
content should use solid elevation tokens (`card` / `popover`) instead.
- Same root cause as the workarounds in #47996 and #48314.
- The “View full cell content” control lives in SQL Editor results /
Report `QueryBlock` (`ResultCell`), not Table Editor. It only renders
when the value is an object/array, contains a newline, or is longer than
60 characters, and it stays `opacity-0` until you hover the cell.

## To test

Short path in Studio (light and dark):

1. **Expand button over cell text (clearest repro)** – SQL Editor, run:
   ```sql
   select repeat('x', 80) as name;
   ```
Hover the result cell. The expand control should appear over the text;
hover the button itself and confirm the fill is solid (no `x`s showing
through). Same control is what Report snippets use.
2. **Any default Button** – Top nav **Connect** (or any bordered default
button). Hover: solid fill.
3. **Select** – Project picker or a Settings form select. Trigger hover
/ open fill stays opaque.
4. **Command menu trigger** – Hover the header search / Cmd-K control;
match default Button.
5. **Skip to content** – Tab once on Studio. Skip link hover stays solid
over the page behind it.
6. **Editor tabs regression** – SQL / Table Editor tab strip should
still look grey in light mode (not washed white).
