Sean Whalen e104f1118c Land 10.0.3 changes on master (#785) 
PR #784 was stacked on the #783 branch and its base was never retargeted to
master, so it merged into fix/mailsuite-2.2.1-empty-address instead of master.
master therefore has 10.0.2 (#783's squash) but is missing the 10.0.3 changes.

This re-lands exactly that delta — the Reply-To/Delivered-To parser fix, the
ES/OS Reply-To header flattening, and the Splunk/OpenSearch/Grafana failure
dashboard fixes, with the version bumped to 10.0.3. No mailsuite re-bump (the
>=2.2.1 floor is already on master from 10.0.2).

"""Tests for parsedmarc.postgres — the PostgreSQL output backend.
The pure timestamp/contact-info helpers are tested directly. The
``PostgreSQLClient`` save methods are tested with psycopg mocked at the SDK
boundary (``parsedmarc.postgres.psycopg``); the assertions check the SQL and
the bound parameters that a real PostgreSQL server would receive, plus the
real-sample round trip, so the tests fail if the dict-key mapping regresses.
