feat: add WCAG AA accessibility app-wide, fix CloudKit container config, remove debug logs

- Add VoiceOver labels, hints, and element grouping across all 60+ views
- Add Reduce Motion support (Theme.Animation.prefersReducedMotion) to all animations
- Replace fixed font sizes with semantic Dynamic Type styles
- Hide decorative elements from VoiceOver with .accessibilityHidden(true)
- Add .minimumHitTarget() modifier ensuring 44pt touch targets
- Add AccessibilityAnnouncer utility for VoiceOver announcements
- Improve color contrast values in Theme.swift for WCAG AA compliance
- Extract CloudKitContainerConfig for explicit container identity
- Remove PostHog debug console log from AnalyticsManager
