hurkicorgi 1ac5513d2c Role-based access: admin vs superadmin
- Credentials provider now resolves two distinct accounts from env:
    SUPERADMIN_USERNAME / SUPERADMIN_PASSWORD → role "superadmin"
    ADMIN_USERNAME      / ADMIN_PASSWORD      → role "admin"
  The role is carried through the JWT and Session callbacks so the UI
  and API can gate on it. Types extended via types/next-auth.d.ts.
- lib/auth.ts exports requireRole(minRole) and sessionRole(session).
- /api/players POST rejects "op" and "deop" with 403 unless the caller
  is superadmin. All other player actions (whitelist add/remove, ban,
  pardon) remain available to both roles.
- lib/use-role.ts (client hook) exposes role / isSuperadmin / authed
  for UI gating without duplicating session typing.
- PlayerManager: Add-OP button and per-row Deop action are hidden or
  disabled for non-superadmin; when a regular admin is viewing the
  Ops tab, a banner explains the read-only state.
- PlayerDrawer: Make Op / Deop button disabled with tooltip for
  non-superadmin; whitelist, ban, pardon unchanged.
- Navbar: subtle role pill next to the user name ("Super" for
  superadmin amber-tinted, "Admin" for admin).
- Migration note: the existing ADMIN_* credentials now log in as the
  restricted admin role. Set SUPERADMIN_USERNAME + SUPERADMIN_PASSWORD
  in .env.local to retain operator-management ability. A placeholder
  superadmin account was generated in .env.local; the password is in
  the commit terminal output only, not the repo.
