fix(esp-box): Fix example IMU vector calculation on ESP-BOX

[finger563]

Description

• Update the esp-box/example to rotate the gravity vector depending on the box type, since the original ESP-BOX has a different IMU orientation on board.

Motivation and Context

Ensures the output of the example is the same across ESP-BOX and ESP-BOX-3

How has this been tested?

Build and run esp-box/example on ESP-BOX and ensure that in the default screen orientation, the gravity vectors on screen point in the right direction.

Pull Request Overview

This PR updates the ESP-BOX example to rotate the gravity and computed vectors when running on the original ESP-BOX, ensuring consistent output across ESP-BOX and ESP-BOX-3.

• Introduce a box_type check to conditionally swap and flip the gravity vector.
• Apply the same conditional rotation logic to the vx and vy components.

• There are no tests covering the new IMU orientation adjustment; consider adding unit or integration tests to verify the gravity vector and computed vector rotations for different box types.

         auto box_type = box.box_type();

[Copilot]

[nitpick] Consider extracting the box-type check and vector rotation logic into a shared helper function or moving the box_type declaration closer to both uses to reduce duplicated code and improve readability.

Suggested change

	auto box_type = box.box_type();
	if (box_type == espp::EspBox::BoxType::BOX) {
	std::swap(gravity_vector.x, gravity_vector.y);
	gravity_vector.y = -gravity_vector.y; // flip y axis
	}
	gravity_vector = adjust_gravity_vector(gravity_vector, box.box_type());

[Copilot]

[nitpick] The swap-and-flip pattern is duplicated for both the gravity vector and the (vx, vy) calculations; extracting this transformation into a reusable helper would avoid duplication and make future adjustments easier.
