chore(deps): pull flow-editor 0.1.1 — false-positive dirty fix

Updates fai_studio_flow_editor pin from 51f9a1d to 8b918f8.

Upstream fix: the editor's dirty-detection compared
_code.text against a snapshot taken before CodeController
normalisation, so opening any flow whose loaded text the
controller silently rewrote (trailing-newline handling, YAML
fold markers, line-ending normalisation) immediately read as
dirty. Clicking a different file in the list then raised the
"Discard unsaved changes?" prompt even though the operator
hadn't typed anything.

The package now compares _code.fullText (the canonical
post-processed value) against a baseline captured AFTER the
text assignment. Comparing fullText-to-fullText eliminates
the spurious diff.

Version: 0.51.1 → 0.51.2
