actuators: add center to Actuators::parseJson

[dakejahl]

Noticed warnings in the console

     8.434 Warning: Unknown 'function': "center" - Vehicle.ActuatorsConfig - (Actuators::parseJson:496)
     8.434 Warning: Unknown 'function': "center" - Vehicle.ActuatorsConfig - (Actuators::parseJson:496)
     8.434 Warning: Unknown 'function': "center" - Vehicle.ActuatorsConfig - (Actuators::parseJson:496)

The PWM_AUX_CENT${i} parameters came in with PX4 in PX4/PX4-Autopilot#25897.

What is odd is we get the warning in QGC, but the UI still works properly. Then what is the purpose of this code?

Pull request overview

Adds support for the new PX4 actuator per-channel parameter function "center" (e.g. PWM_AUX_CENT${i}) so QGroundControl stops logging “Unknown 'function': center” warnings when parsing the actuator config JSON. Also introduces a new top-level build.sh helper script.

Changes:

• Recognize "center" in Actuators::parseJson and map it to a new enum value.
• Add ChannelConfig::Function::Center to the actuator output channel config enum.
• Add a root-level build.sh script to configure/build/run QGC (Qt auto-detect + venv-installed CMake).

File	Description
src/Vehicle/Actuators/Actuators.cc	Parses "center" function for per-channel parameters to avoid “unknown function” warnings.
src/Vehicle/Actuators/ActuatorOutputs.h	Extends ChannelConfig::Function enum with Center.
build.sh	Adds a new developer build script (currently appears unrelated to the PR’s stated actuator-focused scope).
