--- BEGIN ISSUE ---
Unable to access Manage Domain for a transition domain
### Current Behavior

Logged in as a full access user I manually created a domain that just had domain and domain info, but no application. When going to its Manage Domain page via the django admin domain object I got a 500 error and the logs showed an Exception was thrown.  This was to simulate a transition domain and looks like this bug would affect analysts too. 

### Expected Behavior

Expected as I am full access to not see a 500 error going to the manage domain page. Nothing should have crashed.

### Steps to Reproduce

1. Log in as full access or admin user
2. Create a domain with a domain information object 
3. click the manage domain button on the Domain object
4. see a 500 error

### Environment

_No response_

### Additional Context

This line "if requested_domain.domain_application.status not in valid_domain_statuses" in the error message above is the cause of the problem. it should not be checking domain application and needs to check domain information instead.
