test(vault): Docker test suite for 100% external dep coverage

Infrastructure:
- Dockerfile.test: Python 3.12 with ALL extras + liboqs native build
- docker-compose.test.yml: pgvector + test runner containers
- Usage: docker compose -f docker-compose.test.yml up --build

New test files:
- test_postgres_integration.py: 22 tests covering all StorageBackend
  methods (store, get, list, search, update, delete, restore, chunks,
  provenance, collections, count, find_by_cid)
- test_pq_crypto.py: 9 tests for ML-KEM-768, ML-DSA-65, hybrid
  encryption, FIPS KAT (keypair, roundtrip, tamper detection)
- test_cli_full.py: 11 tests for CLI commands via CliRunner (init,
  add, search, list, status, verify, health, expiring, collections,
  export)
- test_ollama_openai.py: 7 tests (Ollama unit parsing + OpenAI
  mocked embed with AsyncMock)

Bug fixes found by integration tests:
- postgres.py: escape '{}' in SQL JSONB defaults for .format()
- postgres.py: parse ISO string to datetime for asyncpg TIMESTAMPTZ

Docker result: 705 passed, 2 skipped (Ollama service), 0 failures.
Local result: 663 passed, 44 skipped, 0 failures.
