Issue Summary

When copying a team-managed project from one organization to another using the cloud-to-cloud (C2C) migration tool, the project filter is migrated as private/editable. For context, team-managed projects shouldn't allow their board filters to be edited, since it can break functionalities, such as the timeline view of team-managed projects.

Steps to Reproduce

1. Create two organizations, for example: "Org A", and "Org B".
2. Create a team-managed project in Org A, say "Project X".
3. Copy "Project X" from "Org A" to "Org B" by performing a cloud-to-cloud migration.
4. Once the copy is done, "Project X" will be available on "Org B", but the board filter will be listed as a private filter and available for editing.
   • This can cause further problems, such as breaking the timeline view of team-managed projects: 
     • Edit the filter to fetch data from any other project, and the timeline will become inaccessible. 

Expected Results

The project filter shouldn't be available as a private filter, it should be hidden and blocked from editing, as every team-managed project filter is. 

Actual Results

The filter is available as private/editable. 

Workaround

There's currently no workaround, to avoid breaking any functionality, don't edit the filter mistakenly available for editing after the C2C migration.
