…3 chain complete_ingestion_task opened a DB session via get_db() but never closed it, leaking a connection on every ingestion (it is the terminal task of the v1.3 chain). Wrap its body in try/finally so the session is always closed, matching copy_files_task and validate_imas_task. validate_imas_task was a stub that always set VALIDATED without validating, and the v1.3 ingestion chain never ran it, so v1.3 silently ignored validation.auto_validate / error_on_fail that v1/v1.1/v1.2 honor. The task now runs the same schema Validator v1.2 uses, sets VALIDATION_FAILED and (when error_on_fail) re-raises to abort the chain before COMPLETED. The v1.3 endpoint inserts the validation step into the chain when auto_validate is set.
to_model_with_path passed the SQLAlchemy URI TypeDecorator (imported from .types) to sha1_checksum instead of a simdb.uri.URI, so sha1_checksum raised AttributeError on uri.scheme for any IMAS file. Construct the URI via the urilib.URI parser, matching from_data / from_data_model.

This PR introduces simulation ingestion via Celery background workers.
When simulations are uploaded through the new v1.3 API endpoint, file copying and status tracking are now handled by Celery tasks (copy_files_task chained with complete_ingestion_task) rather than blocking the HTTP request.
The ingestion pipeline tracks status though the following: QUEUED → COPYING → COPIED → VALIDATING → VALIDATED → COMPLETED, with failure variants.
