[BB-5429] Added date configuration to Schedule & Details settings page

[farhaanbukhsh]

Description

Adds the ability to configure Schedule & Details settings page with the ability to show dd/mm/yyyy format. Default setting maintains existing behavior and doesn't introduce anything new.
Why:
Some areas of the world operate with the day-first: dd/mm/yyyy rather than mm/dd/yyyy.
