Set “Confirmed accessible” as first/default dismiss reason

[Copilot]

The dismiss workflow defaulted to False positive because reason ordering drove default selection in multiple UIs. This updates the canonical reason order so Confirmed accessible is first and therefore selected by default when no prior reason exists.

• Canonical reason ordering (PHP source of truth)

  • Reordered IgnoreUI::get_reasons() so accessible is first.
  • Retains existing reason keys and translatable strings; only ordering/default behavior changes.

• Issue Modal default alignment (React)

  • Updated DismissPanel initial fallback from false_positive to accessible so modal behavior matches canonical ordering.

• Jest fixtures + behavior coverage

  • Updated shared dismiss reason fixtures to reflect new label/description text and ordering.
  • Added assertion that new dismissals submit accessible as the default reason.
  • Updated helper tests to verify first option ordering and current accessible copy.

// admin/class-ignore-ui.php
return [
	'accessible' => [
		'label'       => __( 'Confirmed accessible', 'accessibility-checker' ),
		'description' => __( 'Reviewed and verified to meet accessibility requirements.', 'accessibility-checker' ),
	],
	'false_positive' => [ /* ... */ ],
	'remediated' => [ /* ... */ ],
];
