fix: edge case bugs + toggle lyrics from player bar and lyrics button

Bugs fixed:
- play-at: stop current playback before jumping to queue index
- playNext retry: use break instead of return to ensure stateChange emits
- sendVoiceData: skip if disconnecting to avoid errors during teardown

UI: player-left and lyrics button now toggle lyrics page (open/close)
