The client.ServerVersion method in the moby/client module defines
an output struct that's separate from the API response. These output
structs are not designed to be marshaled as JSON, but the CLI depended
on them defining `json` labels, which it used to format the output
as JSON (`docker version --format=json`); as a result, the JSON output
changed in docker v29, as it would now use the naming based on the Go
struct's fields (`APIVersion` instead of `ApiVersion`).

In future, we should consider having a `--raw` (or similar) option for
the CLI to print API responses as-is, instead of using client structs
or CLI structs for this (this would also make sure the JSON output does
not inherit client-side formatting of fields).

For now, let's create a struct for formatting the output, similar to what
we do for the client-side information.

In the expanded view there is a separate image entry per each tag.

Fix a bug which caused no entry to be added for untagged images.

Previously when no terminal was attached the width was assumed to be 80.
This is too short for most image names which truncated the names when
output was redirect (for example to `grep`).

This disabled the name truncation if the terminal width can't be
determined.

In non-expanded view, untagged images should only be displayed when the
--all flag is explicitly provided by the user.

Previously, untagged images were accidentally always shown in the
non-expanded view regardless of the --all flag setting.

The `Components` weren't actually copied to the output struct.
