fix(monitoring): status-page covers all standalone apps + restore who.mana.how routing

Audit revealed status.mana.how was probing only the unified mana-app
path-routes (mana.how/{module}) plus a couple of GPU services. None
of the standalone deployments were monitored, and three probe targets
were stale.

Changes:

- prometheus.yml blackbox-web: drop mana.how/{context,who} (context
  module was dropped 2026-04-29; mana.how/who never existed —
  /who is a standalone stack on its own subdomain). Add the eight
  hosts that DO have separate deployments today: whopxl, manavoxel,
  memoro (landing), cards (Phase-1 spinoff), who.mana.how/cantina,
  npm (Verdaccio).
- prometheus.yml blackbox-api: add memoro-api/health,
  memoro-audio/health, who-api.mana.how/api/decks,
  admin.mana.how/health (admin's root is auth-walled, only /health
  returns 200).
- prometheus.yml blackbox-gpu: add gpu-llm.mana.how/health (was
  missing; gpu-stt/tts/img/video were in, gpu-llm was somehow not).
- cloudflared-config.yml: restore who.mana.how → :5092 +
  who-api.mana.how → :3092. The DNS CNAME points at the Mini tunnel
  but the route entries had been lost during a previous compose
  cleanup, so every who.* request was hitting the catch-all 404 and
  the standalone Bun stack was effectively orphaned at the edge
  (PM2 + LaunchAgent all healthy on Mini, just no public route).

Live state after rollout: status.mana.how shows 57/59 services UP,
the two remaining DOWN are pre-existing — photon-self (Phase-2c
cross-LAN routing limitation, documented in PLAN_OPTION_C.md) and
whopxl-web (container not running on the Mini, separate issue).
