Ping-Min Lin 1ee88e0fee feat(studio): show Realtime on High Availability projects in staging (#51372)
## What kind of change does this PR introduce?

Feature, limited to staging and local.

## What is the current behavior?

On High Availability projects, Studio always disables Realtime: the
Realtime pages and the Publications pages show an "unavailable" message,
the table editor's "Enable Realtime" checkbox is disabled, and the
project home shows Realtime as disabled.

## What is the new behavior?

A new `useIsRealtimeUnavailable()` hook treats Realtime as unavailable
only on High Availability projects outside staging and local (via
`IS_STAGING_OR_LOCAL`). Those four places use it instead of checking
`high_availability` directly.

- **Production:** unchanged.
- **Staging and local:** Realtime behaves as on standard projects.

## Additional context

Whether a High Availability project is actually registered as a Realtime
tenant is gated separately on the platform side. Until then, the pages
render but Realtime connections for that project fail.

Tests: a new `resolveRealtimeUnavailable` test, and the
`TableRealtimeToggle` and `resolveRealtimeServiceStatus` tests updated
for the renamed parameter.
