Rewrite moonlock from Python to Rust (v0.4.0)

Complete rewrite of the Wayland lockscreen from Python/PyGObject to Rust/gtk4-rs for memory safety in security-critical PAM code and consistency with the moonset/moongreet Rust ecosystem. Modules: main, lockscreen, auth (PAM FFI), fingerprint (fprintd D-Bus), config, i18n, users, power. 37 unit tests. Security: PAM conversation callback with Zeroizing password, panic hook that never unlocks, root check, ext-session-lock-v1 compositor policy, absolute loginctl path, avatar symlink rejection.
