Show property instructions in required field popups and separate instruction-edit permissions

Please let admins separate:

  • who can edit a property value
  • from who can edit the property’s instructions/documentation

We also need property instructions to appear where users actually enter data — especially in required field popups, such as when moving a deal to Closed Won.

Ideal experience

A user should be able to:

  • see the instructions
  • edit the property value
  • not edit the instructions themselves

This would improve data quality, reduce confusion, and make required fields much more useful in real workflow
