[Enhancement] Improve joystick support

While working on #2412, I realised that joystick support needs quite some work.

• Global parameters for deadzone and max_deadzone should be used for all joystick inputs. (Perhaps adding some settings in the menu also)
• A resolution parameter should also be used to avoid too many networking calls. (the difference between current input and last input needs to be a minimum size before network call)
• I fixed some code in that PR that lead to the joystick input of 2 where joystick should have a maximum of 1. I suspect that pattern is replicated in other places.

Ideally we want to handle the deadzones and resolution for each different joystick in the event handler directly so we don't have the same snippet of code repeated in many places in the codebase.

Start with the joystick handling shown in src/screens/crew6/helmsScreen.cpp around the linked code, then trace the event handler and other joystick input paths. Compare how deadzones, maximum deadzones, resolutions, and network calls are handled; done means establishing a consistent approach across the identified inputs and verifying that joystick values stay within the intended range.
