Manan GuptaandJoshen Lim 6a0518dd86 fix(studio): forward HA flag to project-creation pre-flight checks (#50902)
## Summary

- Fixes MUL-1678: toggling High Availability on in the project-creation
wizard 400'd for orgs that are HA-entitled but not enrolled in the "V3
rollout ramp" feature flag on the backend, because two pre-flight
endpoints Studio calls before project creation didn't know about HA and
hit the ramp check the real create-project call already bypasses.
- Threads `highAvailability` through
`useOrganizationAvailableRegionsQuery` (`GET
/platform/projects/available-regions`, sent as
`high_availability=true|false` on the query string) and
`useProjectCreationPostgresVersionsQuery` /
`useAvailableOrioleImageVersion` (`POST
/platform/organizations/:slug/available-versions`, sent as
`high_availability` in the body), including their query-key cache keys
so HA and non-HA responses for the same org/provider/size don't collide.
- Wires the (already form-tracked) `highAvailability` value into every
call site: `ProjectCreationForm.tsx`, `RegionSelector.tsx`, and a new
`highAvailability` prop on `PostgresVersionSelector.tsx` passed from
`InternalOnlyConfiguration.tsx`.

## Problem

The project-creation wizard's HA toggle is wired into the actual
project-create request, but two pre-flight calls Studio makes before
that (available regions, available Postgres versions) had no way to
signal HA, so the backend's ramp-flag gate rejected them for HA-entitled
orgs outside the ramp.

## Solution

Add an optional `highAvailability` field end-to-end on the Studio side:
query hook variables, cache keys, request serialization, and the
components that already track the toggle via `useWatch`.
