fix(audit-wave-9): adopt StatusPill for berth + user status badges

- Extend StatusPill with berth (available/under_offer/sold) and user
  (enabled/disabled) variants so every "this thing is in state X" pill
  shares one primitive and palette.
- Swap berth-card, berth-detail-header, berth-columns from ad-hoc
  bg-green-100 / bg-yellow-100 / bg-red-100 Tailwind tuples to
  <StatusPill status="...">.
- Swap UserList Active/Disabled <Badge> and user-card Inactive pill to
  StatusPill; Super-Admin chip kept as a domain-specific accent (violet).

Closes ui/ux M1+M2.
