Implement Ship Movement Physics

[AndersonGACFilho]

Description
Implement the physics-based movement for the player ship.

Tasks

1. Classes
   • Create ATIRPlayerController.
   • Create ATIRPlayerPawn.
2. Movement Logic (UTIRMovementComponent)
   • Implement Inertia/Drift mechanics (AddForce vs AddInput).
   • Implement Acceleration/Deceleration curves.
   • Implement Banking (Visual roll when turning).

Acceptance Criteria

• Ship accelerates with "weight" (not instant).
• Ship drifts slightly when input stops.
