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) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

+"""
+Tests for the before_request authentication / authorization hook in app.py.
+
+The hook is expected to:
+  - Return 401 for unauthenticated requests to /api/* (except /api/auth/*)
+  - Return 403 for peer-role sessions trying to access non-/api/peer/* routes
+  - Allow admin sessions through to any /api/* route
+  - Allow peer sessions through to /api/peer/* routes
+  - Block admin sessions from /api/peer/* routes (peer-only zone)
+
+Fixtures are deliberately kept in this file so they remain self-contained,
+but they delegate to the same helpers as test_auth_routes.py.
