feat: configure and inspect DRM outputs

+transforms are `normal`, `rotate_90`, `rotate_180`, `rotate_270`, `flipped`,
+and their rotated flipped variants. Output configuration is applied at startup
+and on hotplug; live configuration reload remains deferred.

 hidden unless the session explicitly opts in, because an input method can
