// wxDialog / wxMessageBox / wxTimer Tests - modal dialogs, message boxes and timers that
// KiCad uses for alerts, prompts and animations. Uses the element registry for semantic
// element identification.
//
// Determinism: no waitForTimeout. Readiness via waitForWxApp (canvas visible + registry
// populated, fails loudly). The Dialogs tab switch is done by clickTab, which internally
// polls the registry until the tab reports selected, so the fixed post-switch sleep and the
// silent clickByLabel fallback are gone. Static states (initial view, an open modal, a
// settled/closed dialog, a stopped timer) use stableShot, whose baseline comparison
// retries until the state renders and stabilises — this replaces the blind settle sleeps and
// also deterministically gates the following click (the OK button only exists once the modal
// has rendered). Mid-run timer screenshots (the label increments once a second while the
// timer runs, so no two frames are stable and they asserted nothing) are dropped; the timer
// is screenshotted only in its static initial and stopped states. Where an OK click is not
// preceded by a stabilising screenshot (the full-flow test), waitForRenderedByLabel gates it.
