Default to :latest tag for OCI skill install references (#4430)

When a user runs `thv skill install ghcr.io/org/skill` without a tag,
go-containerregistry defaults to "latest" internally but String() omits
it. The raw user input was passed to oras-go's registry.Pull which
requires an explicit tag, causing a confusing "Bad Gateway" error.

Build the qualified OCI reference from the parsed nameref.Reference,
appending `:latest` only when the user omitted a tag. Also change the
pull error status from 502 to 400 since a bad reference is a client
input error, not an upstream gateway failure.
