feat: Implement local profile name search fallback

- Updated `js/searchView.js` to augment NIP-50 relay search with a local scan of cached profiles.
- `performProfileSearch` now iterates `nostrClient.activeMap` (locally cached videos) to find unique authors.
- It retrieves profile metadata using `app.getProfileCacheEntry(pubkey)`.
- It matches queries against `name`, `about`, `nip05`, and `lightningAddress`.
- Local results are merged with relay results, ensuring robust search functionality even if relay connections are unstable.
- Preserved existing NIP-50 relay search logic.
