Renders each plane via true pinhole projection through a shared
CameraModel instead of the old cosine-compression formula, adds
independent horizontal/vertical pointing drift, and supports generating
a deliberately-offset nominal z (vs. true z) per plane for tolerance-
recovery testing in later tasks.

MeasurementPlane now carries a z_tolerance (uniform tolerance mechanism)
instead of the removed pixel_scale/viewing_angle_deg fields.
ReconstructionResult.pointing_angle_deg becomes horizontal/vertical fields
to match the beam's two independent tilt degrees of freedom.

GeometryCalibration now performs true perspective forward/inverse
projection (with genuine keystoning) around a shared CameraModel, paired
with a CameraModelTolerance that will drive ModalFitter's per-field
fixed/refined behavior in a later task.
