Detect charging status by measuring current flow with configured INA battery sensor (#5271)

* INA219 charging detection

minimal implementation: if there is a configured INA219 sensor for battery monitoring we can take the current flow across the shunt resistor to know if we are charging the battery - negative milliamps indicate charging

* Update Power.cpp

added comments and 2 extra defines to disable and swap detection direction

* Update Power.cpp

fix disabled case

* move getCurrentMa() to new CurrentSensor class

* Fix memory leaks by adding missing `free()` calls before early returns in `MQTT::onReceive` (#5439)

This fix addresses memory leaks in the `MQTT::onReceive` function by ensuring that dynamically allocated resources (`e.channel_id`, `e.gateway_id` and `e.packet`) are properly freed before each early return. Previously, these resources were only freed at the end of the function, leaving them unhandled in certain exit paths. Adding the missing `free()` calls prevents memory leaks and ensures proper resource cleanup in all scenarios.
