fix(KONFLUX-4956): redact sensitive header info from logging

[rh-rahulshetty]

This PR adds a preprocessing to mask sensitive information from headers (like Authorization,Set-Cookie, X-API-Key, Cookie) before logging it into debug output. The header values are replaced with keyword <REDACTED>.

Log Output after masking:
