Alaister Young 0ddf2006d3 [FE-4337] feat(studio): block pause, restore, and add-ons on High Availability projects (#49990) ...

Studio-side guard for Multigres (`high_availability`) projects,
mirroring the platform API guard from supabase/platform#37527. Pause,
restore/PITR, and add-on affordances now show a clear "unavailable on
High Availability projects" state instead of failing with a 400 after
the click.

**Added:**
- Pause project button is disabled on HA projects with a tooltip
- Scheduled backups tab short-circuits to an HA empty state (matches the
existing PITR tab). Per-row Restore buttons are also disabled with a
tooltip as defense in depth, since BackupItem is reusable
- Restore to new project shows an HA admonition ahead of the permission
/ PG15 / physical-backup checks
- Add-ons page shows a page-level HA notice, all three rows are locked
with a tooltip, and the side panels are not mounted on HA so
`?panel=pitr|ipv4|customDomain` deep links are inert
- Component tests for `PauseProjectButton` and `BackupItem`, plus unit
tests for the new `isHighAvailability` branch in `Addons.utils.ts`

**Changed:**
- Add-ons rows are now consistent: the IPv4 row uses the same padlock
tooltip as PITR and custom domain instead of a tooltip on the badge.
Same disabled-reason strings as before, just surfaced via the padlock on
non-HA projects too
- `BackupItem` tooltip text extracted into a `getTooltipText()` function
(mirrors `PauseProjectButton`)
- `HighAvailabilityDisabledSectionNotice` accepts a `className`

Detection reuses the existing `useIsHighAvailability()` hook, which the
rest of Studio already treats as the Multigres signal.

## To test

Use an HA project (`project.high_availability === true`) and a normal
project.

HA project:
- Settings > General: "Pause project" is disabled, tooltip reads
"Pausing is unavailable on High Availability projects"
- Database > Backups > Scheduled backups: HA empty state, no "No backups
yet" / daily backup copy
- Database > Backups > Restore to new project: HA admonition, no restore
controls
- Settings > Add-ons: notice at the top, padlock on all three rows with
per-row tooltip, clicking rows does nothing, and `?panel=pitr` /
`?panel=ipv4` / `?panel=customDomain` open nothing

Normal project (regression):
- No "High Availability" strings on any of the above pages
- Pause button enabled (or disabled only for its usual reasons, e.g.
paid plan)
- Add-on rows open their side panels on click and via `?panel=pitr`
- Scheduled backups tab shows its normal list / empty state

## Summary by CodeRabbit

- **Features**
- High Availability projects now clearly indicate when scheduled
backups, backup restoration, project pausing, IPv4, PITR, and custom
domains are unavailable.
- Added explanatory notices, disabled controls, and tooltips throughout
affected settings and backup screens.
- Restore-to-new-project workflows now provide guidance to contact
support when unavailable.

- **Bug Fixes**
- Improved consistency of availability messaging across High
Availability project settings and database backup actions.
