feat: rename History tab to Library and show local library items

- Rename bottom navigation 'History' to 'Library'
- Add Local Library section showing scanned tracks below downloaded tracks
- Add source badge to each item (Downloaded/Local) for clear identification
- Add new localization strings for Library tab and source badges
- Local library items can be played directly from the library tab

 - **Duplicate Detection in Search Results**: "In Library" badge shows on tracks that exist in your local library
   - Matches by ISRC (exact match) or track name + artist (fuzzy match)
   - Toggle indicator visibility in Settings > Local Library
+- **Unified Library Tab**: History tab renamed to Library, now shows both Downloaded and Local Library tracks
+  - Source badge on each item (Downloaded/Local) to identify the source
+  - Local Library items shown in a separate section when enabled
+  - Play button to open local library tracks directly
 - **Cloud Upload with WebDAV & SFTP**: Automatically upload downloaded files to your NAS or cloud storage
   - Full WebDAV support (Synology DSM, Nextcloud, QNAP, ownCloud)
   - Full SFTP support (any SSH server with SFTP enabled)

 ### Changed
 
 - Cloud upload passwords are now stored in secure storage instead of SharedPreferences
+- Spotify client secrets are now stored in secure storage instead of SharedPreferences
+- Extension HTTP sandbox now enforces HTTPS and blocks private IPs resolved via DNS
+- Extension file sandbox now validates paths using boundary-safe checks
+- WebDAV now defaults to HTTPS; insecure HTTP requires explicit opt-in
+- WebDAV error messages are now localized in the UI
