Revert to the original button-based approach for color manipulation.
The reactive slider implementation was causing infinite loops and page
reloads. Buttons provide stable, predictable behavior.

Track when applying our own changes via isApplyingRef to prevent the color
update effect from resetting sliders when we trigger the change ourselves.
This properly breaks the infinite loop while maintaining reactive behavior.

Refactor manipulation panel to track a base color and apply all manipulations
sequentially from that base, rather than continuously stacking manipulations.
Sliders now reset to 0 when color changes externally (e.g., from color picker).

Provide undefined as initial value to useRef hooks for debounce timers to satisfy TypeScript strict mode requirements.

Remove redundant "Apply" buttons and make all manipulation sliders (lighten, darken, saturate, desaturate, rotate) update the color in real-time with 300ms debouncing. This provides a smoother, more intuitive user experience.

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.
