fix(platform): remove auto-fix identity selection and fix feed loading race condition

- Remove problematic $ensureActiveIdentityPopulated() that auto-selected identities
- Add user-friendly $needsActiveIdentitySelection() and $getAvailableAccountDids() methods
- Fix missing updateActiveDid implementation in CapacitorPlatformService
- Resolve race condition in HomeView initialization causing feed loading failures
- Improve TypeScript error handling in ContactsView invite processing

Addresses team concerns about data consistency and user control for identity selection.
