Add a media-server-style "I dropped files in my folder, hit refresh" control to
the Songs toolbar. Refresh triggers an incremental /api/rescan and reuses the
existing /api/scan-status poll for live progress: a 3-state button (idle /
"Scanning..." while listing / "Scanning N/M" once counting) with a title tooltip
showing the current file + percent. A scan already running (the Settings buttons
or a background pass) is reflected on the button too. On completion it emits
library:changed so the grid reloads, and shows an honest, never-punishing
fbNotify toast (bottom-right, suppressed while in a song). No backend change --
same machinery the Settings rescan already drives. The precise "N added" count
is a follow-up.
