Redesign UI with modern dark theme and improved styling

- Unified color scheme using CSS variables across all pages
- Fixed spacing issues in verse display (removed <br> joins for rich view)
- Updated all HTML pages with proper HTML5 structure
- Added responsive design with mobile breakpoints
- Created shared stylesheet (styles/page.css) for form pages
- Fixed unclosed div tag in scripture_response
- Improved typography with serif fonts for scripture text
- Added verse container cards with hover effects
- Inline dark background to prevent white flash on navigation

All endpoints remain backward compatible with existing functionality.
