Subject: [PATCH] test(accessibility): improve confirm dialog test coverage and
 refactor media state helper

Expand accessibility tests for ConfirmDialog to assert dialog semantics,
ARIA attributes, and visible destructive actions using test IDs. Refactor
expectMediaState helper to check both UI control state and underlying
media signals for more robust playback state detection.
