updated the Generic Report's date range to use MUI Date Pickers matching the Session Details Report style. I changed the date state from string to Date objects, added a format function for the API, and replaced the old text fields with proper calendar pickers. The Search columns text field and Date Range inputs now have consistent height styling. All other filter and aggregation fields remain at normal size for proper alignment. The reset button and template save/load functions were updated to handle the new date format correctly.
