Subject: [PATCH] fix(certificates): improve ASN.1 time parsing and handle edge
 cases

- Added TypeScript ignore directive to suppress type checking in the utility file.
- Refactored the time parsing logic to use Number.parseInt for better clarity.
- Adjusted the flow to throw an error for invalid ASN.1 time formats, ensuring robustness in certificate expiration date extraction.
