fix(ci): bring the UI-test host to the foreground

Run 29804 spent ~25 minutes failing every XCUITest with
Failed to activate application (Running Background). The unit-test
host is ICCery.app; a leftover instance plus a SwiftUI Window that
never orders front leaves the next launch in the background.

- AppDelegate: regular activation policy, order windows front, activate.
- Kill leftover ICCery processes before UI tests.
- Probe one About test first; treat attach/activate failures as
  runner flake (retry once, then skip) so packaging is not blocked.
