Fix datepicker functionality for Bootstrap 5 x-editable

- Updated Gruntfile to use npm bootstrap-datepicker instead of bundled version
- Fixed DPGlobal reference from bdatepicker to datepicker
- Changed mode from inline to popup to ensure date input type is used
- Fixed missing type assignment in editable element initialization
- Enhanced input2value function with fallback logic to extract dates from dates array
- Added comprehensive debugging and error handling
- Datepicker now properly opens, captures selections, and submits formatted dates
