feat(player): sleep timer and delayed start via long-press on play/pause (#270)

Add scheduled pause and resume timers in the player store, cleared on stop
and track changes. Long-press opens a compact preset modal anchored above
the transport row; one-tap presets plus custom minutes. Portaled countdown
badge on the play button; clear the long-press click guard when the modal
closes so the first play/pause click works after scheduling.
