fix(logging): let callers see through the journald formatter wrapper

CI caught what local testing could not: two existing tests in
test_logging_config.py assert that setup_logging() selected a
StructuredFormatter or a ContextualFormatter, by checking the console
handler's formatter directly. Wrapping that formatter to tag each line with
its syslog priority makes those assertions false.

They passed locally and failed on the runner because the wrapper is applied
only when JOURNAL_STREAM is set -- absent in a terminal, present in CI. An
environment-dependent break, which is the kind that gets shipped.

The wrapper now exposes the formatter it delegates to, and those two tests
look through it. They are about which formatter format_type selects, and that
behaviour is unchanged; only the object they have to reach for moved.

Verified both ways this time: 39 tests pass with JOURNAL_STREAM set and with
it unset.
