feat: add footer and fix TypeScript build errors

Add comprehensive footer component with:
- Four-column responsive layout (About, Resources, Documentation, Community)
- Links to all major features and GitHub repositories
- Copyright notice with dynamic year
- Attribution to Pastel CLI and David Peter
- MIT License link
- Built with acknowledgments

Fix TypeScript compilation errors:
- Remove all references to `comingSoon` property in accessibility/page.tsx
- Remove all references to `comingSoon` property in palettes/page.tsx
- Clean up conditional rendering logic

All features now properly linked and accessible.
Build now completes successfully for Docker deployment.
