Make all fields readonly when state s changed to closed including work notes

[Priyanka_77]

I want to make all the fields read only including work notes on hr case form when state is change to closed.

Put a deny-unless write ACL on the table with active = true as condition. Deny-Unless ACLs are evaluated first. If the case isn't active, nobody can write to any field on the table.
