refactor(sway): manage swayidle as a user unit; drop logind override

- New dot_config/systemd/user/swayidle.service, pulled in by
  sway-session.target alongside mako/display-watcher/poweralertd. Same
  lifetime as the rest of the session: starts after graphical-session,
  restarts on failure, stops on logout.
- Drop the swayidle exec from sway config (was unmanaged background
  process with no restart, no logging hookup).
- Revert etc/systemd/logind.conf overrides: swayidle handles idle-lock
  directly via Wayland ext-idle-notifier, so the logind IdleAction
  belt-and-suspenders is redundant. Run just etc-reset
  /etc/systemd/logind.conf on the host to restore pristine.
