Remove 3 redundant hardcoded nodes (Standard/VACE/LoRA), keeping only the
Dynamic node. Add total_sequences INT output (slot 0) for loop counting.
Add structured error handling: _fetch_json returns typed error dicts,
load_dynamic raises RuntimeError with descriptive messages, JS shows
red border/title on errors. Add 500ms debounced auto-refresh on widget
changes. Add 404s for missing project/file in API endpoints.

If the original error (e.g., disk full) also prevents ROLLBACK from
executing, catch and suppress the ROLLBACK failure so the original
exception propagates cleanly and the connection isn't left in a
permanently broken state.

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

- Fix NameError: pass state to _render_vace_settings (tab_batch_ng.py)
- Fix non-atomic sync_to_db: use BEGIN IMMEDIATE transaction with rollback
- Fix create_secondary() missing db/current_project/db_enabled fields
- Fix URL encoding: percent-encode project/file names in API URLs
- Fix import_json_file crash on re-import: upsert instead of insert
- Fix dual DB instances: share single ProjectDB between UI and API routes
- Also fixes top_level metadata never being updated on existing data_files
