Enhance job logging and UI updates

- Implement job logging functionality to track progress and events for each job.
- Add a new section in the job card to display session logs with detailed entries.
- Update job statistics to include pages fetched, pages found, and assets processed.
- Modify the UI theme and text for better clarity and aesthetics.
- Adjust tests to validate new logging features and ensure proper event handling.
