fix: integration and E2E test correctness after auth enforcement

config_manager: make per-file copy errors non-fatal during restore
  (resolves test failures when /app/config/* is not writable by test runner)
test_live_api.py: fix NameError (_req.Session not requests.Session)
test_negative_scenarios.py: replace raw requests.* with authenticated _S.*
  (all endpoints now require auth; unauthenticated calls return 401)
wg/conftest.py: fix wg_server_info — public key is at /api/wireguard/keys
test_admin_navigation.py, test_peer_acl.py: add .first to ambiguous locators
  to avoid Playwright strict-mode errors when desktop+mobile nav both mount
