Enrich domains, IPv4 addresses and MD5 hashes using Proofpoint ET Intelligence.

Uses the v1 API with Authorization header authentication. IP and domain queries return reputation plus passive DNS pivots; MD5 queries return sample details. IPv6 is rejected before querying because the service contract is IPv4. max_results defaults to 25 (1-100). Reputation scores are retained as context, including score zero, and do not change source IDS flags.

Review updates: Maps the documented file_size field to the structured file size-in-bytes relation, retaining zero-byte values.

Configuration and example requests are documented in documentation/expansion/proofpoint_et_intelligence.md. The source attribute and UUID are preserved, enrichment objects reference the source, and new attributes use to_ids=false.

Validation: 30 passed, 1 warning in 0.91s from pytest tests/test_proofpoint_et_intelligence.py, plus Black, isort, flake8 and whitespace checks. Provider responses are mocked; authenticated live API calls have not been exercised.
