A play can take seconds before audio starts (esp. Plex, whose resolve downloads
the whole file) with no feedback today. Add a source-agnostic loading indicator:
- A loading flag keyed to PENDING_PLAY_ID, raised at the top of play_audible
(before the Plex/Qobuz/local resolve — single chokepoint, covers auto-advance)
and cleared by the poll loop when the requested track's audio actually starts
(position > 0). Cleared on every play-error early-return and force-cleared on
queue-finished / peer-controller / ephemeral-stop so it never sticks.
- Watchdog: force-clear after 45s if the engine accepted a play that silently
never advances (undecodable-but-valid file) — otherwise the spinner is eternal.
- Spinner on three surfaces driven by NowPlayingState.loading: now-playing bar
(cover overlay + play/pause button), the active track row's play cell, and the
album big play button (gated to the album actually being launched).
Audio backend / playback routing untouched. The spinner only communicates the
wait; the underlying Plex fetch latency is fixed separately (progressive streaming).

Add the second of the four switchable now-playing bar layouts plus the
4-layout architecture behind it.
ShellState.npb-mode (0=New, 1=Classic) drives mode-conditional columns in
PlayerBar; the transport cluster is extracted into TransportControls.slint and
IconButton/PlayButton into primitives/BarControls (PlayButton gains a `circle`
prop) so both layouts share them without duplicating the popups. The choice
persists via UiPrefs.npb_mode ("new"/"classic") — restored on startup, written
on the "Now Playing view" menu select.
Classic = the Tauri arrangement: transport LEFT (plain play glyph, leading
track-info, inline add-to-playlist + favorite-with-state), glass song card
CENTRE, actions + volume RIGHT. SongCard.glass is a contained card capped at a
fixed 520px; the audio stamp is ABSOLUTELY pinned to the card's right edge
(cover 56 | song info that truncates with ellipsis | stamp 140) so it stays
flush right regardless of the text layout. Track info fires from both the
title click and the transport (i). Classic uses the full-size audio stamp; the
backend LED reads PIPEWIRE.
