Pull request overview

This PR updates simtools’ dependency-version testing and configuration to avoid hardcoded version expectations, improves pytest failure reporting configuration, and updates integration test configs and the dependency catalog to align with the latest simtools-tests tag.

Changes:

• Refactor unit tests to derive expected matrix sizes/tags from dependency_versions.yml instead of hardcoding specific versions.
• Update integration test configs for camera efficiency validation to include an nsb_spectrum input.
• Bump simtools-tests tag to v0.37.0, add changelog fragments, and adjust pytest reporting flags.

Ignoring the failing CORSIKA7 build. That should not have been triggered (will be fixed in #2480 )
