Fix model photo upload, and give network devices the model link the page assumed
Three faults around vendor-model photos, found while looking at why an uploaded
image did not appear.

Saving a model was blocked after uploading a photo. The Image URL field was
type="url", and an upload sets it to an application path such as
/api/models/image/model-120.png. Native url validation demands an absolute URL
with a scheme, so the browser refused to submit the form with "Please enter a
URL" for a value the page had just written itself. The field is now type="text",
which is what it always needed to be: it holds either a full web address or a
path on this server. documentationurl stays type="url".

The upload button did not appear when adding a model, only when editing one.
That was deliberate - the photo is stored as model-<id>.<ext>, so it cannot be
sent before the record has an id - but it reads as a missing feature, and the
hint explaining it was easy to miss. A photo chosen while creating is now held
and uploaded as soon as the model is saved, and it is dropped if the dialog is
cancelled, so it cannot land on the next model created in the same session.

Network devices could never show a photo. NetworkDeviceDetail.vue binds its hero
image to networkdevice.imageurl, but networkdevices carried only vendorid, with
no link to a catalog model, so nothing could populate it - a feature that looked
present and could not work. Machines, PCs and printers have carried
modelnumberid since July. This adds the same column and relationship, the
to_dict branch that exposes modelname and imageurl, the field on the API, and a
Model selector on the form so the link can actually be set.

The migration is guarded the same way employees0002photo is: on a fresh database
the tables come from the SQLAlchemy models, which already declare the column, so
an unconditional add fails with "duplicate column name". The foreign key is
created only on databases that can add one by ALTER; routing it through
batch_alter_table made Alembic's column sort raise "Circular dependency
detected" on the fresh-database test.

Deploying this needs `flask db upgrade` and `flask plugin upgrade-all` on the
server, not just a file copy.
