fix(ui): timestamps in logs, proper call debounce, no cross-calling

- Copy/Share log now includes HH:MM:SS timestamps
- callInProgress stays true until call resolves (setup or hangup),
  preventing multiple taps from firing multiple place_call offers
- Block place_call when there's a pending incoming call
- leaveVoice clears all call state (callInProgress, pendingCallId)
