Joseph Doherty 033b3700c4 test(mqtt): Mosquitto TLS+auth fixture + env-gated plain live suite
Adds the MQTT driver integration-test project: an eclipse-mosquitto fixture running
auth AND TLS (allow_anonymous false on both listeners), a mosquitto_pub-based JSON
publisher emitting retained messages, a cert/password generator script whose output is
gitignored, and a live suite gated on MQTT_FIXTURE_ENDPOINT that skips clean offline.

The fixture is never anonymous by design: an anonymous broker would let the driver's
TLS/CA-pin and auth paths go untested, and those fail silently. The CA-pin leg carries
its own falsifiability control (a foreign CA generated in-process must be rejected).

Live gate on 10.100.0.35: 7/7 passed. It found a driver defect, reported not fixed
here (src/ is out of this task's scope): MqttConnection.ConnectAsync RETURNS NORMALLY
when Mosquitto rejects a CONNECT as not-authorized -- MQTTnet 5 does not throw on an
unsuccessful CONNACK, so a wrong broker password yields DriverState.Healthy from
InitializeAsync. The auth-negative test therefore asserts the invariant that holds
either way (no session is ever established) and documents the finding.

<!-- OTOPCUA0001 (arch-review 07/C-1): this suite invokes driver capability methods DIRECTLY to
exercise wire-level behavior against a real broker — the analyzer's documented intentional
case ("move the suppression into a NoWarn for the test project"). Not a resilience-dispatch
gap. Same suppression as the S7 / AB CIP integration suites. -->

Direct reference (not merely transitive through the driver) because the tests
publish into the fixture broker with their own raw MQTTnet client — the
unauthored-topic test has to emit traffic the DRIVER never emits.

Docker/ is DELIBERATELY not copied to the output directory (the sibling Modbus /
S7 suites copy theirs because their tests read simulator profile JSONs at
runtime; nothing here does). Copying it would also drag Docker/secrets/ — the
generated broker password hash and the CA private key — into bin/, i.e. out of
the one directory .gitignore protects.
