• Bumped MQTTnet (and related) package versions across projects.
• Replaced all IManagedMqttClient usages with IMqttClient, updating factories, subscriber/sender logic, and connection handling.
• Adjusted integration and unit tests to align with the new client API and payload handling.

• The class MqttClientFactory does not exist in MQTTnet v5; you should use new MqttFactory().CreateMqttClient() instead.

        return new MqttClientFactory().CreateMqttClient();

• Extraneous quotes after the closing brace are causing a syntax error; remove the stray ''.

[nitpick] The ConvertPayloadToArray helper is duplicated across multiple test classes; consider moving it into a shared test utility to reduce duplication.

@skotl would you mind check this out. As far as I can tell it works when I run it locally. It would be great if you could manually confirm it works. At some point I will add an integration tests for this too.
