test(display): de-flake the dock harness re-dock assertion (#154)

tools/monitor-fallback.nix flaked at the #148 reload-mid-dock step: after
a lid-closed `hyprctl reload` re-lights the disabled Virtual-1 panel, the
watcher's enforce_dock_intent re-disables it — but only on the loop's 1s
idle tick, because re-enabling an existing connector emits no
`monitoradded` and the chatty IPC events `continue` past reconcile. Under
this softGL VM's load (swaync crash-loops against the absent Vulkan
device) that idle tick is starved, so the re-dock lands ~15-20s out —
right on the old timeout=15.

An instrumented run confirmed the mechanism is correct: dockMode=true is
read, `action=re-dock` fires, the panel is re-disabled (it just missed the
bound). Fix is the bound, not the watcher: 15s → 45s, in line with the
test's own 20-30s waits. Harness now green end-to-end (~61s).

Not a product bug and independent of the #150 extraction (the built
transition/keyboard tools have byte-identical store paths across it).
