convex-js PR 161: Fix Clerk session refresh auth (#54114)

## Summary

Fix `ConvexProviderWithClerk` so Clerk session replacement triggers Convex auth setup again.

The Clerk adapter already rebuilds its token fetcher when org context changes, but it does not currently react to Clerk `sessionId` changes. In Expo apps using `@clerk/expo`, signing out and signing back in can replace the Clerk session while Convex keeps using the previous token fetch closure. This can leave `useConvexAuth()` loaded but unauthenticated until the app reloads or the provider is manually remounted.

Fixes #156.

## Changes

- Include Clerk `sessionId` in the auth context values that rebuild `fetchAccessToken`.
- Preserve the existing behavior of not depending on `getToken`, since Clerk Expo’s `useAuth` hook is not memoized and previously caused an auth loop.

## Follow-up note

I noticed `fetchAccessToken` also reads `sessionClaims?.aud` without including a primitive derived value in the callback dependencies. I left that unchanged here to keep this PR scoped to Clerk session replacement, but it may be worth considering separately if the Convex integration/JWT-template mode can change during a mounted provider lifetime.

## Verification

- `npm run typecheck -- --pretty false`
- `npm run build`
