fixes: tag assign stale body, board placeholder, plugin pending, bucket activate

- Context menu tag toggle reads fresh body from state.cards — was
  overwriting with stale snapshot, dropping existing tags (e.g. #done)
- Board empty-state centered with flex (vertical + horizontal)
- Plugin settings: batch toggles via Apply button, single reload
  instead of one reload per toggle
- New bucket creation activates it directly on the board
