Ethanfel b499eb4dfd Fix 8 bugs from second code review ...

HIGH:
- Fix JS TypeError on empty API response: validate keys/types are arrays
  before using them; add HTTP status check (resp.ok)
- Fix BEGIN IMMEDIATE conflict: set isolation_level=None (autocommit) on
  SQLite connection so explicit transactions work without implicit ones

MEDIUM:
- Fix import_json_file non-atomic: wrap entire operation in BEGIN/COMMIT
  with ROLLBACK on error — no more partial imports
- Fix crash on non-dict batch_data items: skip non-dict elements
- Fix comma-in-key corruption: store keys/types as JSON arrays in hidden
  widgets instead of comma-delimited strings (backward-compat fallback)
- Fix blocking I/O in API routes: change async def to def so FastAPI
  auto-threads the synchronous SQLite calls

LOW:
- Fix missing ?. on app.graph.setDirtyCanvas in refreshDynamicOutputs
