Add srdwm's own native session-lock screen (blur, PAM auth)

A real ext-session-lock-v1 implementation drawn by the compositor
itself, not a hand-off to an external locker process: a live-blurred
background, PAM authentication on a background thread, and its own
config surface (lock_config.rs) rather than hardcoded appearance.
