feat(pf-frame,pf-win-display): leaf primitives for the lid-closed first-frame fix

Three leaf-crate additions the IDD-push capturer (pf-capture, plan §W6 C6)
builds on — committed ahead so the capture-crate extraction and the HID
compose kick can land on top:

- pf-frame session_tuning::DisplayWakeRequest — RAII PowerCreateRequest/
  PowerSetRequest(PowerRequestDisplayRequired + SystemRequired), the
  service-grade 'someone is watching this screen' assertion (visible in
  powercfg /requests), held for a capture session so the console cannot
  drop into display-off mid-stream. Object-lifetime, unlike the
  thread-bound ES_* flags in on_hot_thread. Prevention only: no power
  request turns an already-off display back on — that wake is input's
  job (the virtual-mouse compose kick).

- pf-win-display win_display::desktop_bounds() — the virtual-desktop
  bounds as the union of every ACTIVE CCD path's source rect. From the
  CCD database (global), NOT GetSystemMetrics (a per-session view), so
  a non-console-session host still aims HID absolute coordinates at the
  console's real layout.

- pf-win-display console_session_mismatch() — the session guard from
  3d9b3290, copied into the leaf so pf-capture reads it as a peer
  instead of reaching into the orchestrator (relocation authored by the
  W6 extraction session).
