Subject: [PATCH] [FIX] calendar: Add force_save to send values to server

- Create Event (Where All Day is Set to False)
- Edit Event > Check 'All Day', make it 'Recurrent'

An error occurs because a mandatory field is not set (`stop_date`).

It is possible to work around the issue by doing:
- Check 'All Day'
- Save
- Make it 'Recurrent'

However, the result should not depend on the order we perform the
action. To solve this we send data to server with `force_save`.

Fixes #27269
Closes #33068

closes odoo/odoo#35758
