feat: add workspace session, auth, and store infrastructure (#8194)

## Summary
- Add `teamWorkspaceStore` Pinia store for workspace state management
(workspaces, members, invites, current workspace)
- Add `workspaceApi` client for workspace CRUD, member management, and
invite operations
- Update `useWorkspaceSwitch` composable for workspace switching logic
- Update `useSessionCookie` for workspace-aware sessions
- Update `firebaseAuthStore` for workspace aware auth
- Use `workspaceAuthStore` for workspace auth flow

## Test plan
- [x] 59 unit tests passing (50 store tests + 9 switch tests)
- [x] Typecheck passing
- [x] Lint passing
- [x] Knip passing

Note: This PR depends on the `team_workspaces_enabled` feature flag
being available (already in main).
