findings group O: chooser Enter + infobar close fixes (wx → 15e5315244) with repro specs and uipolish guards

- tests/kicad/footprint-chooser-confirm.spec.ts (O-2): typed filter + Enter
  confirms the chooser and a footprint is placed.
- tests/kicad/infobar-dismiss.spec.ts (O-3): real click on the older-version
  infobar close glyph dismisses it; GAL rect shift logged.
- uipolish app/spec: rounded-neg-radius (O-1 guard), enable-propagation (O-3),
  dom-nav-keys Enter/ArrowDown → CHAR_HOOK with TEXT_ENTER once (O-2).
