fix: improve E2E auth resilience and diagnostics (#33)

- Wait for Authentik popup to fully load (domcontentloaded + networkidle)
  before interacting with form elements
- Add explicit waitFor on username/password fields with 15s timeout
- Enable screenshot capture on test failure for better diagnostics
- Increase auth setup timeout to 60s to accommodate slow IdP responses

The auth setup was failing because the popup form elements weren't
ready when Playwright tried to fill them — this adds proper load
state waits between each interaction step.
