Added a deprecated tag to old method. Added a check to add and edit shift that sees if there are any conflicts with an approved time off. Added the same checks from add shift to edit shift. Added methods for addShiftIgnore and editShiftIgnore.

Changed the startDate and endDate to LocalDate for easier evaluation and integration. Added a conflictsWithTimeOff method that checks if a date conflicts with a time off, note this doesn't check if it's been approved though.

admin availability null error, can't navigate from staff -> sched (staff loads different panels) pop ups still need to be hooked up

Fixed some bugs that would cause edited shifts to return nothing, and the edited availability to return nothing.

Added a clause to the add shift method that checks the availability and makes sure that the start is later than the end.

After a change in the database that made email addresses unique, caused a bug where new employees on the app to not be added after the first one.
