Subject: feat(sway): auto-lock on idle and before suspend

- logind: IdleAction=lock, IdleActionSec=5min. systemd emits a lock
  signal at 5min idle (session becomes locked from logind PoV; swayidle
  listens and invokes swaylock).
- swayidle: lock at 5min, blank display at 6min, lock before sleep.
  Closes the gap where lid-close or manual suspend would wake to an
  unlocked session.
- swaylock: add -i (--ignore-empty-password) to ignore accidental Enter.
- meta/wayland: add swayidle.
