feat(logging): add HTTP page fetch logging and enhance click-TT proxy functionality

- Introduced a new logging mechanism for HTTP requests to click-TT/HTTV pages, improving traceability and debugging capabilities.
- Implemented a proxy endpoint for iframe embedding, allowing direct HTML retrieval with enhanced error handling and validation for input URLs.
- Updated the frontend to include a new navigation link for the click-TT feature, accessible to admin users.
- Added a new route for the click-TT view in the router configuration.
