Data changes to prepare for workspaceMember page (#10439)

Workspace Member will get their own record page in the future.

This PR lays backend changes to prepare for this:
- Settings most fields on WorkspaceMember as system fields
- Renaming workspaceMember/workspaceMemberId to
forWorkspaceMember/forWorkspaceMemberId as it conflicts with the morph
relationship, if we want to be able to add a workspace member as
favorite
