chore: Remove cyclic imports

• Please check this box if this contribution uses AI-generated content (including content generated by GitLab Duo features) as outlined in the GitLab DCO & CLA

Description

This removes several cyclic imports which were manually ignored by the compiler.

• Importing only the type definition instead of requiring the module will avoid all issues that arise from cyclic dependencies during runtime.
• JobLogRefresher has been changed to accept a JobLogCache parameter, instead of relying on the singleton.
