Fix hashtag preferences loading and profile persistence issues

- Migrated Kind 0 profile metadata storage to unified `profileCache.js` with partitioning and persistence.
- Added `defaultDTag` for hashtag preferences in `cachePolicies.js` to ensure consistent key resolution.
- Updated `hashtagPreferencesService.js` to use `profileCache` and implemented legacy data migration.
- Added `handleEvent` to `NostrClient` to centrally ingest Kind 0 events into the cache.
- Updated `authService.js` and `cache.js` to delegate profile operations to the unified cache system.
- Added `PROFILE_METADATA` schema to `nostrEventSchemas.js`.
