Add uptime to statistics menu

Fixes prusa3d#4392

Add uptime to the statistics menu.

* Add a new function `RecordUptime` in `src/common/app_metrics.cpp` to record the uptime in hours.
* Modify `RecordRuntimeStats` in `src/common/app_metrics.cpp` to call `RecordUptime`.
* Update `src/common/appmain.cpp` to call `RecordUptime` in the `app_run` function.
* Add a new line to display the uptime in hours in the statistics menu in `src/gui/screen_menu_statistics.cpp`.
* Add a new member variable to store the uptime and a new method to update the uptime in `src/gui/screen_menu_statistics.hpp`.
