bug in api_view and permission_view updates in deployment

**Describe the bug**
During deployment, the endpoints permissions are updated automatically depending on how they are defined in the code:
- the api_view table is updated with new endpoints.
- the permissions in permission_view are updated.

I have notices several problems with this update:
- There is no check about if an endpoint has been deleted or its permissions changed. Only new endpoints are created in api_view.
- If the project include a custom role which is not in cornflow, this role seems to be ignored when updating permissions in permission_view.

**To Reproduce**
Steps to reproduce the behavior:
1 modify the ROLES_WITH_ACCESS attribute of an endpoint
2 redeploy
3 check permission_view table. The new permission won't appear.

Second problem:
1 create a new endpoint (or change the name of an endpoint)
2 add a custom role in ROLES_WITH_ACCESS attribute
3 redeploy
4 check permission_view table. The new permission won't appear.

**Expected behavior**
Deployment should update all permissions including custom roles.
Outdated endpoints should also be deleted (this part is less important since those endpoints won't be accessed anyway)

**Metadata (please complete the following information):**
- cornflow version 1.2.1
- other libraries:

**Additional context**
Add any other context about the problem here.

Trace the deployment logic that updates the api_view and permission_view tables, focusing on endpoint ROLES_WITH_ACCESS handling. Reproduce the redeployment cases by changing permissions and adding a custom role, then verify that changed permissions and custom roles are reflected and that outdated endpoints are removed or otherwise handled as expected.
