fix: permission error message and Android 13+ storage permission

Browse Source 
- Fixed download showing 'Song not found' when actually permission error
- Added permission error type detection in Go backend
- Android 13+ now requests both MANAGE_EXTERNAL_STORAGE and READ_MEDIA_AUDIO
- MANAGE_EXTERNAL_STORAGE opens Settings (system-level)
- READ_MEDIA_AUDIO shows dialog (app-level, resets on clear data)
- Proper permission check before showing 'granted' status

- Detects existing entries by Spotify ID, Deezer ID, or ISRC
- Replaces existing entry and moves to top of list
- Auto-deduplicates existing history on app load
- **Permission Error Message**: Fixed download showing "Song not found" when actually a permission error
- Now shows proper message: "Cannot write to folder, check storage permission"
- Added `permission` error type detection in backend
- **Android 13+ Storage Permission**: Fixed storage permission not working on Android 13+
- Android 13+ now requests both `MANAGE_EXTERNAL_STORAGE` and `READ_MEDIA_AUDIO`
- `MANAGE_EXTERNAL_STORAGE` opens Settings (system-level, persists across app data clear)
- `READ_MEDIA_AUDIO` shows dialog (app-level, resets on app data clear)
- Proper permission check before showing "granted" status
