[Feature Request]: meshtasticd - Implement TLS MQTT support

Hardware

Linux Native

Firmware Version

2.5.21

Description

I'm unable to establish a connection from portduino to MQTT broker via TLS. A non-TLS connection works.
Tested T-beams on the same MQTT broker and they do connect to both, TLS and non-TLS ports on a broker. Portduino is the only one that has an issue with TLS.

	using MQTTClientTLS = WiFiClientSecure;
	#define MQTT_SUPPORTS_TLS 1
	#endif

WiFiClientSecure needs to be implemented in framework-portduino before this can work 🙏 as that's what PubSub uses to create TLS MQTT connections.
