Added a script to update a beamline

[anubhutisinha04]

This PR introduces a new update script that modifies only the required fields when changes are needed, instead of creating a new object on every update.

The new approach selectively updates specific values, eliminating unintended side effects.

Pull request overview

This PR introduces a new utility script for updating beamline records in the database. The script provides a targeted approach to modify specific fields (service accounts) without recreating the entire beamline object, addressing concerns about unintended side effects from full object replacement.

Changes:

• Added scripts/update_beamline.py to enable selective field updates for beamline records
• Script fetches an existing beamline by PASS ID and updates only the service_accounts field

Thanks for making this script. You had a good idea to handle it separately from beamline creation.

In this case, only the service accounts were updated, but it would be good to point out where someone should inject additional changes, if needed.

I think it would be good practice to show the new object before it gets saved.
