More flexible office-bearer term dates

You can now add an end date to an office-bearer term without needing to include a start date. Previously, this wasn’t allowed — the only way to remove an elder, deacon, or pastor role without a start date was to delete the term entirely.

This wasn’t ideal, as it erased the historical record that the member had served as an office-bearer. It also created issues with visit tracking, since that feature only includes members with current or past terms. If no term exists, visits can't be properly attributed.

While we still strongly recommend recording both start and end dates for all office-bearer terms — to preserve accurate history and improve reporting — this is no longer strictly required.
