Hygiene B4b: extract CameraResolver (dedup triplicated ResolveCamera)

The byte-identical ResolveCamera() (Camera.main -> PrototypeCameraRig fallback) in PlayerInputGatherSystem, BuildSendSystem, and AimReticleSystem now call one CameraResolver.Resolve(); camera-resolution policy lives in one place. Behaviour-identical; compiles clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
