Unify sub-service display formatting for Info status

Change docker images to use name field for all data instead of metrics,
matching the pattern used by torrent stats and VPN routes. Increase display
width for Status::Info sub-services from 18 to 50 characters to accommodate
longer informational text without truncation.

- Docker images now show: "image-name size: 994.0 MB" in name field
- Torrent stats show: "17 active, ↓ 2.5 MB/s, ↑ 1.2 MB/s" in name field
- Remove fixed-width padding for Info status sub-services
- Update version to v0.1.245
