Fix 4 bugs from third code review

- 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
