Review the code quality of the TI Connect certificate tracking implementation in: - src/modules/kbv-ti-connect/main/ti-connect.ts

Focus on: 1. The trackCertificateType function implementation (lines 112-131) 2. The function call at line 174-177 3. Overall code quality, adherence to DDV patterns, and potential issues 4. Whether the implementation follows CONTRIBUTING.md guidelines

Recent changes: - Made certificateType a function parameter instead of hardcoded - Removed tiEnvironment field from tracking data (redundant since we only track in PU) - Removed try/catch block since JWSUtils.deriveJWAFromCertificate handles errors internally - Function only tracks certificates in PU environment (production-like)
