fix: WireGuard peer sync, privileged mode, E2E and integration test correctness

- api/app.py: sync WireGuard server config on peer add/remove (non-fatal)
- docker-compose.yml: add privileged:true to wireguard service
- E2E tests: fix logout selector, DNS IP lookup, wg config DNS line, VIP skip guards,
  badge text selectors, heading .first, async logout wait
- Integration tests: fix 4 tests that sent unauthenticated requests expecting 400
  (now use authenticated session helpers); accept 401 as valid in webui proxy test;
  add password field to service_access validation test
- Remove stale tracked config templates (config/api/api/*, config/api/cell.env, etc.)
  that no longer exist on disk after config layout was reorganised
