Add the staff-operations surface scaffolding and the first group. Session gains
isStaff/isModerator/isAdmin; the menu gains STAFF (admin/editor/moderator) and
MODERATOR (admin/moderator) access levels, plus a StaffGate mirroring PlayerGate.
Dashboard group (over the existing /api/v1/admin, bearer-authed, role re-checked
every request): AdminApi/AdminDto/AdminRepository for GET /admin/dashboard and
PUT /admin/site-mode; AdminDashboardScreen shows site mode, summary counts, and
recent admin activity, with an admin-only maintenance/live toggle.
Verified on emulator against the dev backend: an admin sees the Dashboard entry
(a player does not); counts + audit log render from real data; the site-mode
toggle flips /public/status to maintenance and back to live. MenuAccessTest +2
(8 total), assembleDebug + lint green.
