HM-2383 [UPDATE] List Reservation – Add “Group reservation code”

The hotel receptionist wants to see the Group Reservation Code for each sub-book within the group booking directly on the Reservation List screen so I can easily distinguish which bookings belong to the group and which are regular personal bookings, and to facilitate faster searching/operations.

1. A column called “Group reservation code” has appeared in the List reservation table.
2. For personal bookings within a group booking: the “Group reservation code” column displays the exact group booking code generated when the group booking was created.
3. For personal bookings that are not part of a group booking: leave the GroupBookingCode column blank to avoid confusion.
4. Adding the “Group reservation code” column does not change the data or how existing columns ( FO status, Type, Booking code, Confirm code, etc.) are displayed.
5. When loading the List reservation screen, the “Group reservation code” data is retrieved correctly from the database, matching the information of the created group booking.
6. The “Group reservation code” column interface adheres to the current style (font, color, alignment, responsive at small resolutions).
