chore(studio): editor 0.4.0 — port geometry + endpoint editor + unsaved badge

Picks up fai_studio_flow_editor 0.4.0 (commit fb88926):

 - Connection dots now line up with their inline port-row
   labels (header geometry rewrite so subtitle space is
   always reserved).
 - Inputs endpoint colours its output ports by declared
   type (text / bytes / json / file / number).
 - Selecting the inputs or outputs endpoint opens a
   dedicated editor in the properties panel — add /
   rename / retype / remove without touching YAML.
 - "Unsaved" badge replaces the easy-to-miss 8-px dot;
   filename also colours primary when dirty.

Version 0.53.0 -> 0.53.1.
