Danny White fd01c665e2 feat(studio): move Stripe Projects to connect interstitial (#45862) ...

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Feature update. Resolves DEPR-553.

## What is the current behavior?

Stripe Projects login still uses the older `APIAuthorizationLayout`
surface, so it does not match the newer shared connect interstitial
pattern used by organisation invites and CLI login.

## What is the new behavior?

Moves `/partners/stripe/projects/login` onto the shared
`InterstitialLayout` while preserving the existing `ar_id` account
request lookup, confirmation mutation, wrong-account sign-out path, and
missing-parameter redirect.

The temporary reviewer mocks have been removed after approval.

## Testing instructions

Automated checks run locally:

- `pnpm --dir apps/studio exec prettier --write
pages/partners/stripe/projects/login.tsx
components/layouts/InterstitialLayout.tsx`
- `pnpm --dir apps/studio exec eslint
pages/partners/stripe/projects/login.tsx
components/layouts/InterstitialLayout.tsx`
- `git diff --check`

`pnpm --dir apps/studio exec tsc --noEmit` was also run earlier on this
branch, but still fails on existing unrelated issues in
`components/interfaces/Integrations/Landing/useAvailableIntegrations.tsx`
and `packages/common/marketplace-client.ts`.

Manual Stripe Projects testing requires a real account request. Opening
`/partners/stripe/projects/login` without an `ar_id` redirects to `/404`
by design.

If you need the real flow:

1. Use the Stripe staging provider. In the Stripe CLI flow, run `export
DEV_MODE=true` so the provider is `Supabase_Staging_Env`.
2. From a local project directory, run `stripe projects init` and
complete the Stripe setup flow.
3. Run `stripe projects add Supabase_Staging_Env`.
4. When the browser opens the Supabase authorization URL, keep the
generated path and query string exactly as-is, including `ar_id`, but
replace only the origin with this PR preview deployment origin.

Note: the staging Stripe Projects flow can still incur real Stripe
costs; use the staging provider and coordinate refunds with team billing
if needed.

## Additional context

This is a deliberately small stacked slice toward the broader shared
connect interstitial work.
