Hide member emails from non-admins (#327)

* feat(workspace): sanitize member emails for non-admin users in workspace router

* feat(workspace): add email visibility setting and update member display logic

* fix(workspace): update default value for showEmailsToMembers column to true

* - Removed unnecessary type assertions
- Added anonymous name handling (anonymous_[publicId]) in the API
- Removed placeholder logic
- Reverted null check
- Avoided as unknown cast
