- Bumped the Docling document parser request timeout default from 300s to 600s. Large documents were exceeding the previous 5-minute ceiling and failing with `Timeout`. The value now lives in a single named constant, `DOCLING_PARSER_REQUEST_TIMEOUT_SECONDS` in `opencontractserver/constants/document_processing.py`, referenced by both the Django setting default (`config/settings/base.py` `DOCLING_PARSER_TIMEOUT`) and the `DoclingParser` dataclass field default (`opencontractserver/pipeline/parsers/docling_parser_rest.py` `request_timeout`) so they can't drift apart. Still overridable per-deployment via the `DOCLING_PARSER_TIMEOUT` env var.
