fix(ui): duplicate schedule warning

[adityamkk]

Issue: it is possible to bypass the schedule creation limit by selecting certain options.

Solution: I created a useEnforceScheduleLimit hook in the DialogProvider directory

These hook attempts to add/duplicate a schedule, but displays a warning dialog whenever the schedule limit is breached.
This hook is used in the CalendarSchedules, ScheduleListItem, and PopupMain components.

Hey Aditya, please see the task in the Bug Tracker project and let me know if this explains more about the issue and how it can be fixed. Not sure if that is what your method handles.

LGTM (still need review from Sam, Diego, or Elie) but the loophole seems to be fixed with this PR

[Samathingamajig]

looks good in general, but there's a big chunk of duplicate code that should be reduced (see other comments for more details)

[Razboy20]

Ideally, we should have a standard component for this particular box so we can use it both when adding a schedule normally and when duplicating a schedule.

This is the perfect PR for that! 😄

[Samathingamajig]

looks pretty good, couple of small changes requested to ensure code quality

code works on my machine 👍
