fix: CPU calc, disk card, lifespan, remove Google Fonts CDN, fix doc link

- Fix Docker container CPU % (multiply by num_cpus)
- Add missing Disk usage card to system status grid
- Replace deprecated @app.on_event with lifespan context manager
- Move `import requests` to module level
- Remove Google Fonts CDN dependency from CSS
- Update naming doc URL to real raw Gitea link
