feat(themes): add Vision Dark & Vision Navy colorblind-safe themes (closes #166)

Purple & Gold palette (Deuteranopia / Protanopia / Tritanopia safe). Vision Dark: near-black #0D0B12 + Gold #FFD700 (~14.7:1 WCAG AAA). Vision Navy: deep navy #0A1628 + Gold #FFD700 (~14.5:1 WCAG AAA). New 'Accessibility' group in ThemePicker. Removed stale theme count from aboutFeatures across all locales. This is an initial step toward colorblind accessibility — color variables alone cannot cover all CVD use cases. Structural improvements (secondary indicators, pattern/shape cues) are still needed in future iterations. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
