Added routine for dragging for the time line on the calendar + fixed the alignment of top header items + fixed the text cutting issue on the bottom drop downs
1. fixed the bottom drop down in accordance with the design
2. fixed the fluctuation in the bottom section on changing the month in the calendar  ( when you switch the month the Bottom "Text + " heading moves up and down it should be stable to the change in the calendar month )
fixed the calendar :- right now the month that is active is not highlighted in the month list section now the current month background will change as per the shared design
Restricted the dragging of the time slots behind the current hour mark in case of today.
updated the cursor type to more generic resize pointer
