feat(hub): cross-group search with reuse of existing views

Search page fetches indexes from all groups, then renders consolidated
entries through the existing FilesPanel, VideoApp, and MusicApp
components — no reimplemented views. Groups appear as top-level
directories in the file browser; video/music entries use a synthetic
root with per-entry transport refs for thumbnails and metadata across
groups. Music player lifted to app.js with getConnection(groupId) for
cross-group playback. Connection pool (max 3, LRU eviction) manages
lazy WebRTC connections. All 10 locales updated with search keys.
