Convert patient search to DataTables with AJAX server-side processing

Browse Source 
- Updated Patient::search() to only render view with search query
- Created Patient::search_ajax() method for DataTables AJAX endpoint
- Implemented server-side processing with pagination, sorting, and filtering
- Results ordered by Last Visit DESC by default
- Retrieves all patient data from patient_master table
- Added proper SQL escaping to prevent injection
- Updated Patient_Search_V.php to use DataTables with AJAX remote data
- Added DataTables configuration with 25 rows per page default
- Supports dynamic length menu (10, 25, 50, 100, All)
- Added route for billing/patient/search_ajax endpoint
- Improved user experience with loading spinner and customized messages
