Improve the representation of neutral beam tangency in the toroidal cross-section plotting. #4183

Description of issue / requirement to address

Beam tangency plotting is currently clipping against the port / vessel geometry, leading to incorrect or truncated beam paths in the toroidal view.

dx_beam_duct: float = None """width of neutral beam duct where it passes between the TF coils (m) T Inoue et al, Design of neutral beam system for ITER-FEAT, Fusion Engineering and Design, Volumes 56-57, October 2001, Pages 517-521) """

dx_beam_duct is defined as the full width of the beam, yet in our plotting we treat is as a half-width.

This means the plotted beam is wider than it should be, and this can lead to clipping.

Proposed solution

Adjust the calculation in plot/summary.py to treat dx_beam_duct as full width.
