Enhance datepicker UX: position above input with proper styling

- Added CSS positioning to display inline datepicker above input field
- Enhanced datepicker styling with background, border and shadow
- Improved template with datepicker-above class for better positioning
- Maintains Bootstrap 5 compatibility and inline mode functionality

This provides a better user experience by preventing the datepicker
from appearing below and potentially being cut off by page boundaries.
