Implement privileged event filtering and add comprehensive tests
- Refactored the HandleReq function to improve the handling of privileged events, ensuring that only authorized users can access them based on their authentication status and associated tags. - Introduced a new test suite for privileged event filtering, covering various scenarios including authorized access, unauthorized access, and edge cases with malformed tags. - Enhanced the publisher logic to deny delivery of privileged events to unauthenticated subscribers. - Bumped version to v0.17.18.
