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.

Ensure consistent spacing and alignment between header, main content, and footer:
- Update Navbar to use max-w-7xl and px-8 (matching Footer)
- Standardize all page containers to use px-8 py-12 padding
- Change home page from max-w-5xl to max-w-7xl for consistency
- Update all 12 pages to use consistent padding (px-8 py-12 instead of p-8)
This creates a unified visual alignment across the entire application,
with all content sections (navbar, main, footer) using the same
max-width (7xl) and horizontal padding (px-8).

- Fix method name casing: `simulateColorBlindness` (capital B)
- Add palette generation endpoint integration
**Type Definition Updates:**

- Add PaletteGenerateRequest and PaletteGenerateData types
**Completed Features:**
- Harmony Palettes: Now uses dedicated `/palettes/generate` API endpoint
