SIENTIAPDE-1646

SIENTIAPDE-1646 Merge origin/main into release/SIENTIAPDE-1646

Bring main up to date while keeping this branch's sync execution, PluginStore
runtime and sientia_model (SientiaMLflowRepository/SientiaModel) structure.

Resolution decisions:
- OPC: keep the sync asyncua.sync implementation; port main's server_uri
  validation, e2e race fix (lock held until released) and the new unit tests
  converted to sync.
- Model import workflow (.sientia bundles), joblib/transform flavors and the
  local MLFlowRepository (model_repository.py) are dropped, with their tests,
  docs, metrics, env vars and connectors config.
- Worker: drift/simple_metrics stay pinned to the 'core' runtime; port main's
  HOSTNAME pod id, logger-based prometheus startup and sys.exit after finally.
- values.yaml removed, following main (SIENTIAPDE-1945).
- Deps: keep sientia_model; take main's fsspec/s3fs/botocore/boto3 pins and
  sientia_do>=1.12.2; drop import-only deps (pynacl, cryptography, pymongo,
  python-dotenv, pycaret, joblib, gcsfs).
- e2e: keep sientia_data schema and scenario input files.
