[PM-35063] CXP importation from Apple Passwords does not include application autofill affiliations.

### Steps To Reproduce

As [`issues/2535`](https://github.com/bitwarden/ios/issues/2535#issue-4256410714) states:

1. I created an Apple Passwords item for {an account for} a TestFlight application.

1. I exported that entrant to Bitwarden, via CXP.

### Expected Result

Auto-fill should operate, because the affiliation should remain:

### Actual Result

It is not transferred:

### Additional Context

This is similar to [`ios/issues/1979`](https://github.com/bitwarden/ios/issues/1979#issue-3447024149). To demonstrate, the process is:

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Start with the ImportCXFView flow and the ciphers/import request shown in the flight recorder, then trace how the imported login reaches AutofillCredentialService. Compare the Apple Passwords affiliation with the resulting CXP item, and use the related issues/2535 and ios/issues/1979 for expected behavior. Done means the affiliation is preserved and autofill works for the imported TestFlight credential.
