feat: settings screen, user profile & enhanced clothing attributes

[jvsena42]

Summary

Add a Settings screen with user profile management and API key configuration, expand clothing item attributes (subcategory, fit, material), update AI prompts for men's capsule wardrobe focus, and remove the DRESS category.

Changes

• Settings screen (Android & iOS): Card-based navigation with separate bottom sheets for profile editing and API key management, matching the Pencil design
• User profile: Body type, style profile, age range, climate, and lifestyle preferences stored via DataStore (KMP expect/actual)
• New clothing attributes: Subcategory (per-category options), Fit (slim/regular/relaxed/oversized), and Material (cotton/linen/denim/etc.) added to ClothingItem model, DB schema, and AddItemSheet UI
• Expanded color palette: 8 → 14 colors (added White, Charcoal, Khaki, Tan, Burgundy, Light Blue)
• Removed DRESS category: Migrated existing DRESS items to TOP via SQLDelight migration
• AI prompt updates: All prompts now specify men's capsule wardrobe focus, analyze subcategory/fit/material, and inject user profile context into gap/try-it recommendations
• New data layer: SettingsRepository (DataStore-backed), SettingsViewModel (MVI), platform DI wiring
• About section: Version from PackageInfo/Bundle, Licenses link to GitHub MIT license
