feat(housekeeping): in-client admin panel

Adds the Housekeeping in-client admin panel — a Modtools-adjacent
surface that runs entirely inside the React client, talking to the
emulator over the existing wire instead of a separate REST/CMS layer.

Surface:
- `src/components/housekeeping/` — panel shell + 5 tabs (Dashboard,
  Users, Rooms, Economy, Audit). Each tab drives one domain of the
  matching emulator handlers (find/sanction/admin/economy/catalog/
  hotel-wide).
- `src/api/housekeeping/` — composer/parser orchestration:
  `HousekeepingApi.ts` exposes 30+ typed actions, each one running
  through `runHkAction()` which awaits the shared
  `HousekeepingActionResultEvent` correlated by action key.
- `src/hooks/housekeeping/` — `useHousekeeping` (the public hook),
  `useHousekeepingStore` (useBetween singleton: shared selection +
  audit polling + sanction templates), `useHousekeepingActions`,
  `useHousekeepingConfirm`.
- `src/api/nitro/awaitMessageEvent.ts` — Promise adapter over
  `CommunicationManager.subscribeMessage` with a sync `select`
  callback that snapshots the parser INSIDE the subscribe handler
  before the renderer recycles the parser instance after the
  Promise resolves.
- `public/configuration/housekeeping-texts-{en,it}.example` —
  149 EN + 149 IT i18n keys under `housekeeping.*` for every panel
  string + every server-side error slug the emulator may emit.

Wiring (additive only):
- `src/components/MainView.tsx` — `<HousekeepingView />` mounted
  alongside `<ModToolsView />`.
- `src/api/index.ts`, `src/hooks/index.ts`, `src/api/nitro/index.ts`
  — added the `housekeeping` and `awaitMessageEvent` re-exports.

Wire contract: pairs against the Arcturus PR (#120 on
duckietm/Arcturus-Morningstar-Extended) and the renderer PR (#77 on
duckietm/Nitro_Render_V3). Incoming events 9100..9129, outgoing
composers 9200..9207. Permission gate `acc_housekeeping` enforced
server-side; the panel is hidden client-side via
`housekeeping.enabled` in the runtime ui-config.
