93889ab9bd fix: correct API integration and complete missing features 
Fix API response format mismatches and implement all remaining features:

**API Integration Fixes:**
- Fix ManipulationPanel to use `colors` instead of `results` from API responses
- Fix gradient endpoint to use `gradient` array from API response
- Fix color blindness simulator to use correct field names (`input`/`output` vs `original`/`simulated`)
- Fix text color optimizer request field (`backgrounds` vs `background_colors`)
- Fix method name casing: `simulateColorBlindness` (capital B)
- Add palette generation endpoint integration

**Type Definition Updates:**
- Update GradientData to match API structure with `gradient` array
- Update ColorBlindnessData to use `colors` with `input`/`output`/`difference_percentage`
- Update TextColorData to use `colors` with `textcolor`/`wcag_aa`/`wcag_aaa` fields
- Add PaletteGenerateRequest and PaletteGenerateData types

**Completed Features:**
- Harmony Palettes: Now uses dedicated `/palettes/generate` API endpoint
  - Simplified from 80 lines of manual color theory to single API call
  - Supports 6 harmony types: monochromatic, analogous, complementary, split-complementary, triadic, tetradic
- Text Color Optimizer: Full implementation with WCAG compliance checking
  - Automatic black/white text color selection
  - Live preview with contrast ratios
  - AA/AAA compliance indicators
- Color Blindness Simulator: Fixed and working
  - Shows difference percentage for each simulation
  - Side-by-side comparison view
- Gradient Creator: Fixed to use correct API response structure
- Batch Operations: Fixed to extract output colors correctly

**UI Improvements:**
- Enable all accessibility tool cards (remove "Coming Soon" badges)
- Enable harmony palettes card
- Add safety check for gradient state to prevent undefined errors

All features now fully functional and properly integrated with Pastel API.
