feat: add authentication and authorization system

Backend:
- AuthManager (api/auth_manager.py): server-side user store with bcrypt
  password hashing, account lockout after 5 failed attempts (15 min),
  and atomic file writes
- AuthRoutes (api/auth_routes.py): Blueprint at /api/auth/* — login,
  logout, me, change-password, admin reset-password, list-users
- app.py: register auth_bp blueprint; add enforce_auth before_request
  hook (401 for unauthenticated, 403 for wrong role; only active when
  auth store has users so pre-auth tests remain green); instantiate
  AuthManager; update POST /api/peers to require password >= 10 chars
  and auto-provision email + calendar + files + auth accounts with full
  rollback on any failure; extend DELETE /api/peers to tear down all
  four service accounts; add /api/peer/dashboard and /api/peer/services
  peer-scoped routes; fix is_local_request to also trust the last
  X-Forwarded-For entry appended by the reverse proxy (Caddy)
- Role-based access: admin for /api/* (except /api/auth/* which is
  public and /api/peer/* which is peer-only)
- setup_cell.py: generate and print initial admin password, store in
  .admin_initial_password with 0600 permissions; cleaned up on first
  admin login

Frontend:
- AuthContext.jsx: React context with login/logout/me state and Axios
  interceptor for automatic 401 redirect
- PrivateRoute.jsx: route guard component
- Login.jsx: login page with error handling and must-change-password
  redirect
- AccountSettings.jsx: change-password form for any authenticated user
- PeerDashboard.jsx: peer-role landing page (IP, service list)
- MyServices.jsx: peer service links page
- App.jsx, Sidebar.jsx: AuthContext integration, logout button,
  PrivateRoute wrappers, peer-role routing
- Peers.jsx, WireGuard.jsx, api.js: auth-aware API calls

Tests: 100 new auth tests all pass (test_auth_manager, test_auth_routes,
test_route_protection, test_peer_provisioning). Fix pre-existing test
failures: update WireGuard test keys to valid 44-char base64 format
(test_wireguard_manager, test_peer_wg_integration), add password field
and service manager mocks to test_api_endpoints peer tests, add auth
helpers to conftest.py. Full suite: 845 passed, 0 failures.

Fixed: .admin_initial_password security cleanup on bootstrap, username
minimum length (3 chars enforced by USERNAME_RE regex)
