[Feature] - Read-Only Fields in Object Properties

[b1scuit-thi3f]

Describe the solution you'd like
Setting certain fields to read-only would make sense for a number of objects. For example, globally the ID field and execution count are not fields that should be modified by users, and so should be greyed out, similar to what we do for usernames in the user editor

This would most likely be an additional property for each schema item that could be defined in the manifest (or hardcoded if generating the field via a plugin/system).
