fix(display): docked idle wake + dump without SSH (#127)

Recover from DPMS/lock blackout without a second machine: undock/enable
always issue dpms on; hypridle on-resume and after_sleep run
nomarchy-display-wake (zero-output undock rescue + auto-dump).
nomarchy-display-dump writes ~/nomarchy-display-dump-*.txt (SUPER+SHIFT+D
or Ctrl+Alt+F3 TTY). HARDWARE-QUEUE #127 no longer requires SSH.

V1: nix flake check --no-build. V3: docked idle on AMD box still open.
