Now Playing card on the Music tab; Signal alerts (chime, desktop notification, unread count in tab title and app icon)

- Music: a card with art, seek bar and controls above the albums, artists and playlists
- Signal: chime, optional desktop notification when the app is in the background, (n) in the tab title, app badge; Settings -> Signal alerts (per device)
- README, player test stand-in updated

The link keys live in the `nehub-signal` volume (a Docker *volume*, not a host folder: the bridge runs as user 1000 and a root-owned host folder gives "permission denied"; if you do want a folder, `chown -R 1000:1000` it first): whoever gets into your server can read your chats,
   so only give the **Signal** tab to people you would trust with your Signal (it is one shared account, admins always have it). Signal drops a linked device that is
   not connected for about a month; the hub stays connected, so this only matters if the stack is switched off.
