### Summary
A large ~Ultimate ~self-managed customer reports in [ZD#708643](https://gitlab.zendesk.com/agent/tickets/708643) that 2 approval rules remain on merge requests after compliance frameworks are rapidly changed from projects.
### Steps to reproduce
<!-- Describe how one can reproduce the issue - this is very important. Please use an ordered list. -->
1. Create a project with two compliance framework that includes a approval rule policy
2. Create a merge request in the project
3. In the project, go Security -> Compliance center -> Project (`-/security/compliance_dashboard/projects`)
4. Using the Pencil icon button and toggle fast by deselecting one and selecting other:
5. Observe the merge request approval rules
### Example Project
<!-- If possible, please create an example project here on GitLab.com that exhibits the problematic
behavior, and link to it here in the bug report. If you are using an older version of GitLab, this
will also determine whether the bug is fixed in a more recent version. -->
### What is the current *bug* behavior?
<!-- Describe what actually happens. -->
Merge requests have stale approval rules even when the compliance framework is no longer associated with the project. The approval rules persist and cannot be removed via UI or API.
Customer logs show `PG::UniqueViolation` errors when duplicate approval rules are attempted by overlapping stale jobs.
### What is the expected *correct* behavior?
<!-- Describe what you should see instead. -->
Only the project's current compliance framework associated approval rules should be applied to the MRs. If the framework is no longer associated with the project, the approval rules associated with the framework should be discarded in MR.
### Relevant logs and/or screenshots
<!-- Paste any relevant logs - please use code blocks (```) to format console output, logs, and code
as it's tough to read otherwise. -->
