Wizard: Display customized policy rules in review summary

Previously, when a user selected a compliance policy with tailored rules,
the review page always showed the default profile customizations instead
of the policy-specific customizations.

Root cause: OscapProfileInformation component was only using the profile
endpoint (/oscap/{distribution}/{profile}/customizations) which returns
base profile rules, not the policy endpoint
(/oscap/{policy}/{distribution}/policy_customizations) which returns
customized rules.

Changes:
- Add useGetOscapCustomizationsForPolicyQuery export to backendApi
- Implement dual data fetching in OscapProfileInformation:
  * Profile endpoint: for description and reference ID
  * Policy endpoint: for customized packages, services, kernel args

Fixes the compliance policy customization display bug where edited
policy rules were not reflected in the image build summary.

Add unit tests for compliance policy customizations
