fix(docker): truncate long image names in container table

Fixes #825

Long Docker image names (like Immich postgres containers) were expanding
the entire table row, requiring horizontal scrolling to see CPU/Memory.

Changed the image cell to use:
- Inline style max-width (more reliable in table layouts)
- Block span with truncate class
- overflow-hidden on parent container

Images now truncate with ellipsis at 200px, with full name in tooltip.
