fix: E2E test isolation and analytics consent bugs

- Isolate test web server on port 2349 so E2E tests run alongside Docker
- Use fresh SQLite database per test run via DB_PATH, fixing missing
  roles/audit_log tables from stale migration state
- Fix analytics consent redirect loop when ANALYTICS_ENABLED=false by
  auto-declining consent instead of bare redirect
- Dismiss analytics consent via API in auth setup and RBAC test user
  creation so the consent page never blocks UI tests
- Make Vite port and proxy target configurable via env vars
