feat: queue-ux-improvements (#419)

* feat(queue): add ETA display, equalizer indicator and collapsible now playing

* deleted endsAt and showDuration strings, changed eta update to 30s

* feat(queue): ETA tooltip, persistent Now Playing collapse, EQ bar pause, remove redundant Play icon

* feat(queue): fold ETA into existing total/remaining toggle as third mode

The standalone ETA span next to the track counter is removed; instead the
clickable duration label in the queue header now rotates through three
modes per click: total → remaining → eta → total. Counter (N/M) stays
where it was.

ETA mode keeps the live-feel treatment from the original PR (accent
colour while playing, muted at 50% opacity when paused). The other two
modes use plain accent.

i18n: queue.etaTooltip removed (no longer a separate descriptive label),
queue.showEta added as the action tooltip ('Show estimated end time')
in all 8 locales — matches the showRemaining / showTotal pattern.

* docs(changelog): add #419 queue UX improvements entry

Adds the [1.45.0] / Added entry for this PR's queue panel refinements
(position counter, tri-state duration toggle including ETA, collapsible
Now Playing section, animated EQ indicator).
