Lock Action Card due dates

To prevent accidental changes and to maintain the integrity of their project timelines, we've added the ability to lock Action Card Due Dates. This allows users to better manage projects with fixed deadlines without room for accidental errors.

To edit/lock a date, click the due date and select the "Lock dates" checkbox.

From here, only project owners and admins will be able to unlock the due date.

Thank you to Abby at Perforce, Bennett at Seaboard Solar Operations, and Alexandra at Women's World Banking for providing feedback on this feature.
