Serialize awaited initialization with auth-state changes.

init() can write an older user ID after exchangeCodeForSession() or getSession() resolves. If an auth-state change processes sign-out or an account switch while either operation is pending, the later initialization result can overwrite the current Jam user ID. The catch path can also leave a stored Jam user ID when it sets the session to null. Track an auth-event generation, or use one ordered state-transition path, before applying initialization results and failure cleanup. Add a regression test for a pending session operation followed by sign-out.

In `@src/lib/supabase/AuthProvider.tsx` at line 102, Update AuthProvider
initialization and auth-state handling around init(), exchangeCodeForSession(),
getSession(), and setJamUserId so auth-event transitions are serialized and
stale async results cannot overwrite the current user after sign-out or account
switching. Ensure failure cleanup also clears any stored Jam user ID when the
session becomes null, and add a regression test covering a pending session
operation followed by sign-out.

Fixed the narrow part: the catch path now also clears the Jam user id (and the ref backing it) when init fails, so a failed init after a real sign-in can't leave stale/signed-out user ids on subsequent Jam bug reports (3adaec2).

Declining the broader ask (generation-counter serialization across init/exchangeCodeForSession/getSession/onAuthStateChange, plus a regression test): that race already exists for session/currentUserIdRef in this file pre-dating this PR — this diff only mirrored the existing assignment pattern for the new Jam metadata call, it didn't introduce the race. Reordering the whole auth-init flow is a heavier architectural change than this "add Jam SDK" PR should carry; happy to take it as a separate follow-up if it's worth prioritizing.

@Programcode, confirmed. The init() failure path now clears both currentUserIdRef.current and Jam metadata.

The remaining initialization ordering race predates this PR. The new Jam metadata synchronization can reflect that race, but a serialization change and regression test are larger than this integration change.

Would you like me to open a follow-up GitHub issue for ordered auth initialization and auth-state transitions?

Learning: In `src/lib/supabase/AuthProvider.tsx`, the asynchronous initialization and `onAuthStateChange` ordering race for `session` and `currentUserIdRef` predates the Jam SDK integration. Auth-state serialization and its regression test are intentionally out of scope for the Jam integration pull request and may be handled in a separate follow-up.
