Creating a new appointment from the Gantt view now starts from the current time rounded to the nearest hour instead of defaulting to midnight. This makes new bookings faster and more relevant for users scheduling appointments during the day.

Purpose
=========
Currently when we click on the new button on Gantt view the default start is set to today's midnight which is not relevant.

After this PR
==================
The current DateTime with rounded hour will be set as a default start while creating a new booking through the Gantt view.
