chore(studio): bump editor lock to 0.1.4 (top-align + refresh move)

Stefan reported the editor still centered short files vertically
and the reload icon was still between New and Save — but his
pubspec.lock pinned fai_studio_flow_editor to resolved-ref
7655e0d (0.1.2), which predates both fixes:

 - a7485ca (0.1.3) stretch attempt
 - daf6732 (0.1.4) actual fix via CodeField expands:true +
   refresh moved into the FileList header

Force lock to daf6732 so `flutter pub get` during `fai studio`
build picks up the current state of the editor's main branch
without needing a manual `flutter pub upgrade` step.

Version 0.51.9 -> 0.51.10.
