feat: add long press to shuffle with a wave animation (#888)

* feat: add long press to shuffle with a wave animation to singnify how long to press

* refactor: long-press shuffle cleanup

Follow-up on the long-press shuffle PR: shared hook/overlay, playback parity,
pointer events, broader surface coverage, locales, and tests.

* docs: credit ImAsra for long-press album shuffle (PR #888)

Add CHANGELOG entry and Settings credits for the hold-to-shuffle play
interaction shipped in Psychotoxical/psysonic#888.

* fix: restore playAlbumShuffled and long-press hook wiring

The follow-up merge dropped playAlbumShuffled and reverted the shared
long-press hook in album play buttons, breaking tsc and vitest on PR #888.
