feat: operator admin UI (rooms, bookings, calendar blocks, settings)
Replaces the placeholder page with a real 4-tab admin (Vue 3 + Quasar 2 UMD,
no build). Rooms table with create/edit dialog + publish-toggle + delete;
per-room bookings view; per-room calendar blocks add/delete; operator
settings form (identity, relays, hold, deposit, times, policy).
UMD gotchas honored: no self-closing tags, ${ } interpolation, :style for
typography, static_url_for(path=...). Follows the spirekeeper admin pattern.
