When manually creating an appointment by drag-selecting a time slot in the calendar view, the booking screen opens with Default selected under Date & Time — completely ignoring the time I just selected with my mouse.

Steps to reproduce:

Open the Calendar (week or day view).

Click and drag to select a time slot (e.g. 10:00–12:00).

The manual booking screen opens.

Date & Time is set to Default, overriding my selection with the calendar's default block (e.g. 07:00–15:00 for an 8-hour slot).

Expected behaviour:

The booking screen should open with Custom pre-selected and the dragged time slot already filled in — since the user has already made an explicit time selection.

Actual behaviour:

The drag selection is silently discarded. The appointment is created at the default block time unless the user remembers to manually switch to "Custom" every single time.

Impact:

High — appointments and confirmation emails go out with the wrong time if the toggle is forgotten. This is a UX inconsistency: a deliberate mouse selection should never be silently overwritten by a default.

Suggested fix:

If the booking screen is opened via a drag-selection in the calendar view, automatically set Date & Time to Custom and pre-populate the start and end time from the selection.
