Fix lint issues: err113 and revive unused-parameter warnings
- Add nolint directives for err113 issues with justifications - Fix all revive unused-parameter warnings by renaming unused parameters to _ - Affects test files across certmanager, istiocsr, and trustmanager controllers This reduces lint issues from 29 to 19 (only cyclop issues remain) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
