Subject: [PATCH] fix: image_from_name() dies on duplicate names instead of
 returning wrong type

image_from_name() returned an arrayref when multiple images shared the
same name, but callers (like create_vm) expected a hashref. This caused
$image->{id} to silently evaluate to undef, leading to confusing API
errors downstream.

Now dies with a descriptive message listing the duplicate IDs and
suggesting image_from_uid as the workaround.

Also fixes bare die statements in Images.pm with descriptive messages
and corrects the images() error message (missing "or").
