Smart pointers and memory management cleanup (#10400)

Browse Source 
* Refactor memory management in Syslog and StoreForwardModule

* Implement destructor for Lock

* Refactor RotaryEncoder and PacketHistory to use smart pointers for better memory management

* CH341 should use unique_ptr for improved memory management

* Fix checks in PH

* Improve Syslog::vlogf to handle variable argument lists more safely

* Fix initOk method to use nullptr for null pointer check
