VSN-1976/ Fix action buttons positioning and auto-refresh schedule after trip changes

Issues Addressed

1. Action Buttons Positioning

   • Current behavior: "Add" and "Cancel" buttons are displayed at the bottom of the customization form.
   • Expected behavior: Buttons should be positioned at the top, next to the title "Customized Trip Form" for better accessibility.

2. Schedule Auto-Refresh

   • Symptoms:
     • After customizing a trip, changes are not immediately reflected in the schedule.
     • After duplicating a trip, the schedule does not update automatically.
     • Users must manually refresh the page to see updates.
   • Probable cause: Local state is not synchronized with the schedule display, and there is no automatic refresh after modification operations.
   • Fix: Implemented automatic schedule refresh after trip customization or duplication to ensure changes appear immediately.
