Add an 'Alias / Routing' template to the create-flow gallery that seeds a
minimal name + alias config, and a read-only 'alias -> target' badge on the
Manage Models tab. The capabilities row payload does not carry the alias
field, so the badge resolves targets from GET /api/aliases looked up by name.
