Add HP toggle, new conditions, fix turn order sync bug

- Add DM toggle (default on) to hide player HP bars on player display;
  persisted in activeDisplay Firestore doc for real-time sync
- Add Alchemist Fire and Bardic Inspiration conditions; sort all
  conditions alphabetically
- Fix turn order skipping when participants are deleted, deactivated,
  or killed mid-combat: turnOrderIds was never updated, causing
  handleNextTurn to resolve currentIndex as -1 and snap back to the
  first participant. Now all mutation paths (delete, toggle active,
  HP death/resurrection) keep turnOrderIds in sync and advance the
  turn pointer correctly when the current participant is removed.
