refactor(l4d2-web): remove legacy external overlay type
The workshop + managed-global overlay surface fully covers the
admin-SFTP flow that 'external' was a placeholder for. Drop the type
from the model defaults, builder registry, routes, template, and
tests, and add migration 0004 that deletes any leftover external
rows along with their blueprint and job references.
