fix(e2e): resolve SPA auth race conditions in Robot tests

- Rework Login As Admin: use sessionStorage flag + relative fetch login + polling loop
- Add data-testid to JailDetailPage error render path
- Add Collections library import for Get From List keyword
- Fix /jails API response extraction (returns {items, total} not plain list)
- Change Close Context to Close Browser for proper browser cleanup
- Add domcontentloaded + Sleep + polling to Config test to avoid premature timeout
