feat(studio): editor 0.7.0 — typed wires + animated flow + canvas depth

Picks up fai_studio_flow_editor 0.7.0 (commit 7aeeae7):

 - Wires take the colour of the data they carry. Inputs-
   endpoint edges show their type accent (text=blue,
   bytes=orange, json=purple, file=green, number=amber)
   so the operator can trace flow data by colour alone.
 - Edges entering a currently-running step animate as
   marching dashes in the wire's accent colour. Stops
   when the step completes. The canvas comes alive
   during runs.
 - Canvas backdrop is a subtle gradient (corners recessed,
   centre lit). Nodes get layered shadows; selected nodes
   wear an accent-coloured halo. 180 ms ease-out
   transitions on hover / select / status changes.

Version 0.53.6 -> 0.54.0 (minor bump — first wave of the
2026-feel visual refresh).
