feat(logging): enhance HTTP request logging with additional payload details

- Introduced new fields in the HttpPageFetchLog model to capture request and response headers, bodies, and method for improved logging granularity.
- Updated the logging service to serialize and store these new details during HTTP fetch operations, enhancing traceability and debugging capabilities.
- Modified the clickTtHttpPageRoutes to include the new logging features, allowing for optional payload inclusion in log queries.
