When modifying a section field, lock the ID

When initially building a section the ID of the fields should follow the name of the fields, however, when editing later, a field should be renamable without breaking the code- the ID for the field could be locked to remain the same.

This could either be done after the section has first been “created/published”
OR there could be a smart check to see if the field has already been used in the code, and lock the ID after it has been.
OR We could allow the user a checkbox to “lock” the ID manually when editing the field name
