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.

       **Important distinction:** on AC, hypridle is *not* supposed to
       suspend — only lock (5m) + `dpms off` (10m). Confirm next time with
-      `journalctl -b | rg -i 'Suspending|PM: suspend'` vs hypridle/hyprlock
-      lines so we know DPMS-stuck vs real S3.
-      **Repro / capture (next time, before reboot if possible — SSH/TTY):**
-      1. Dock, confirm dock mode (eDP disabled in `hyprctl monitors all -j`).
-      2. Leave idle past 10 minutes (or force: `loginctl lock-session` then
-         `hyprctl dispatch dpms off`).
-      3. Try external KB key / mouse move — does external wake?
-      4. Unplug external — does eDP return within a few seconds?
-      5. Capture (SSH from another machine if the seat is blind):
-         ```
-         journalctl --user -t nomarchy-display-watch -t nomarchy-display-transition \
-           -t hypridle --since '-30 min'

-         systemd-inhibit --list
-         ```
-      **Pass:** input wakes the external while docked; undock while black
-      restores eDP without power cycle. Related: docking recovery round 8

+      3. External KB/mouse — external should wake (`nomarchy-display-wake`
