Fix logging format: use request path instead of file path, clean timestamp

- Log request paths (/big-file.mkv) instead of file system paths
- Custom timestamp format: YYYY-MM-DDTHH:MM:SSZ (no milliseconds)
- Update serve_file to accept request parameter for proper logging
- Strip gemini://host prefix from logged requests for cleaner logs
- Add time crate for custom timestamp formatting
