Adapt + improve all admin pages to the new design system

Swept the whole housekeeping panel (34 pages) so it's a consistent,
improved adaptation of the old Filament admin rather than bare tables:
- Live status tiles (StatusCard) summarising each page's data — counts
  and stateful metrics (users online, active/permanent bans, pending
  applications, settings, radio shouts, etc.).
- Status pills (admin-badge ok/danger) replacing ad-hoc text: online/
  offline, account/ip ban types, permanent vs timed, command OK/FAIL,
  alert severity & read/new, enabled/disabled, open/closed.
- Sections wrapped in .admin-section with h2 headers; redundant inline
  table styling removed (the global .admin layer handles it).
- alerts/logs/emulator hand-built as the reference pattern; the rest
  via parallel agents that read the schema and preserved every server
  action, query and field name.

Behaviour unchanged (same actions, queries, field names). Verified in a
real authed admin session (prod, amx_test): pages render with live data
(Users tiles show 7 real accounts + online/offline pills), no errors.
tsc 0, vitest 49/49, next build 0.
