Implement a locking mechanism for editing the shared entities in bundles.

Description of the issue

Certain entities within bundles are shared among multiple bundles. For example "Institutions" or "Contact person". As a result, multiple users can edit these entities simultaneously. This could potentially result in updates that are not consistent.

Ideas of solution

A locking mechanism that prevents simultaneous updates and only allows one update at a time based on a timeout. See below:
