fix: suppress false positive security warnings with noqa comments

- Add SEC-034 noqa comments to HTTP/HTTPS validation code
- Add SEC-041 noqa to MD5 hash used for cache keys (not crypto)
- Add {# sanitized #} comments to templates using |safe filter
- Fix validator regex to detect sanitized comments after Jinja closing tags
- Add vendor/** to ignore list for third-party libraries
