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.

- Fix delete_proj not persisting cleared current_project to config:
page reload after deleting active project restored deleted name,
silently breaking all DB sync
- Fix sync_to_db crash on non-dict batch_data items: add isinstance
guard matching import_json_file
- Fix output_types ignored in load_dynamic: parse declared types and
use to_int()/to_float() to coerce values, so downstream ComfyUI
nodes receive correct types even when API returns strings
- Fix backward-compat comma-split for types not trimming whitespace:
legacy workflows with "STRING, INT" got types " INT" breaking
ComfyUI connection type-matching

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
