Add 5 new themes to iOS app (Lavender, Crimson, Midnight, Desert, Mint)

Expanded the theming system from 5 to 10 total themes with comprehensive light/dark mode support. Each new theme includes unique color palettes optimized for visibility and WCAG contrast compliance.

New Themes:
- Lavender: Soft purple with pink accents
- Crimson: Bold red with warm highlights
- Midnight: Deep navy with sky blue tones
- Desert: Warm terracotta and sand palette
- Mint: Fresh green with turquoise accents

Technical Details:
- Created 45 new colorset files (9 colorsets × 5 themes)
- Each theme includes Primary, Secondary, Accent, 2 Backgrounds, and 4 Text colors
- Dark mode colors use 60-90% lightness for high visibility on dark backgrounds
- Consistent text colors across all themes for accessibility
- Updated ThemeManager.swift to include all 10 themes
