hyprlock: disable fingerprint, add battery/weather/notifications

- Disable fingerprint auth (GDM holds the device; hyprlock can't
  claim it, blocking the auth thread).
- Fix date format escaping (single quotes).
- Add battery, weather, and latest mako notification labels.
- Add hyprlock wrapper (crash guard), battery script, notifications
  script, and weather script.
