Make Start Date appear

[bakobagassas]

Issue Description

Fixes #1594

• When doing the usability study, in reference to task " Create an Event that Repeats Three Weeks in a Series", participants often faced a problem in which the start date created on the main page (after picking an Event type within "Create Event"), when they turned on the toggle ("This is a series of Events") the start date would disappear and didnt transfer to the series. The start date selected outside of the modal should transfer into the modal and should still be editable.

Changes

• Only js file, made it so that the event is carried into the box, same as the name and location.
• Carried the date into the occurrence events
• Carried the time too

Testing

• Go to create an event
• Select the program
• Fill out name, location, and date
• Click that it is a series of events
• toggle the weekly repetition
• You should see the name you previously inputted appear as the start date.

The date appears in the multiple-offering modal when toggling 'This series repeats weekly'; however, it's not carried over when you press 'Add Occurrence', which I feel like it should.

I think it would also be good to carry over the time from the initial form into the modal, since that would be a good quality-of-life change and very similar to the date appearing in the modal.

[JohnCox2211]

• The start/end time is not carried over when you press the add occurrence button in the series of events modal
• After saving recurring events in the modal, then exiting the modal to save the event overall, there is a value error: ValueError: time data '4/3/2026 15:00' does not match format '%Y-%m-%d %H:%M'

I don't think this print statement is needed.
