ci: add step-level timeouts and cap E2E hang at 5 min (#67)

- Split single 'Run Full Check Suite' step into named steps so per-step
  timing is visible in the CI UI
- Add timeout-minutes: 20 to the overall job and timeout-minutes: 6 to
  the UI E2E step — previously a stuck xvfb-run could hang for 23+ min
- Add 'timeout 300' to xvfb-run in integration_ui_test.sh so the E2E
  test exits with a clear error instead of hanging indefinitely
