fix: avoid shadowing 'log' package by aliasing import as 'logf'
The 'log' package from controller-runtime was being shadowed by local variables in multiple Reconcile methods, which could lead to confusion and bugs. Renamed the import to 'logf' to clarify usage and prevent name collisions across the codebase and generated scaffolds.
