Closes #1214

Summary

Provides creators with an automated accessibility audit (WCAG 2.1 AA) of their campaign page before publishing.

Acceptance Criteria Met

1. Checker runs on publish or via a Check Accessibility button:
   • Added checkCampaignAccessibility service evaluating WCAG 2.1 AA criteria (Non-text content 1.1.1, Heading structure 1.3.1, Video captions 1.2.2, Color reliance 1.4.1, Contrast minimum 1.4.3, Link purpose 2.4.4, Headings and labels 2.4.6, Language 3.1.1, Labels and instructions 3.3.2).
   • Added "Check Accessibility" button on the Preview step and action bar.
   • Automatically executes on publish ("Launch Campaign" action).
2. Results list issues with fix suggestions:
   • Added CampaignAccessibilityModal dialog presenting detected issues with severity badges, WCAG criterion tags, and actionable fix suggestions.
   • Enables filtering by All, Critical, and Warnings.
3. Critical issues block publish; warnings are advisory:
   • Any critical accessibility issue blocks publishing until resolved.
   • Advisory warnings inform creators but permit proceeding with launch.
