chore(studio): editor 0.6.0 — edge hover/menu + pattern + zoom

Picks up fai_studio_flow_editor 0.6.0 (commit 5ff7a1c):

 - Edges highlight on hover (8 px hit radius around the
   bezier path).
 - Right-click or long-press on an edge opens a Disconnect
   popup. Same on ports + step nodes — long-press is now
   the trackpad-friendly alternative everywhere a context
   menu lives.
 - Background pattern toggle (dots / grid / blank) on the
   bottom-right canvas controls.
 - Live zoom indicator as a tappable % readout — tap to
   snap back to 100 % without losing pan.

Version 0.53.5 -> 0.53.6.
