refactor(device-sync): G.74 — extract helpers + legacy template + fetcher + BrowserRow (cluster) (#641)
Four-cut cluster opening the DeviceSync refactor. 1289 → 1186 LOC (−103). deviceSyncHelpers — uuid, formatBytes, trackToSyncInfo (with the albumArtist-fallback-to-artist logic and the optional playlist context the Rust sync command consumes), plus the SourceTab / SyncStatus / RemovableDrive / SyncTrackMaybePlaylist types. deviceSyncLegacyTemplate — sanitizeComponent (matches Rust's sanitize_path_component) + OldTemplateTrack + applyLegacyTemplate. Lives apart from the general helpers because it's only used by the migration-preview flow and pulls in IS_WINDOWS for path separator. fetchTracksForSource — single async helper that loads the songs for a DeviceSyncSource (playlist / album / artist). Artist sources fan out into parallel getAlbum requests (Navidrome handles them concurrently; the old sequential loop was a ~7 s blocker on 50-album artists). BrowserRow — small button row component used by the source-picker list (playlists / albums / artists tabs). DeviceSync drops the inline definitions plus the direct getAlbum / getPlaylist / getArtist imports that only fetchTracksForSource needed. Pure code move — no behaviour change.
