Description and Purpose

When 1P+2P IPC is enabled, the yaw PI controller reads axisYawF_2P, but the Coleman
transform only updates axisYaw_2P. Update the PI feedback on every timestep so the
2P yaw pitch contribution responds to the measured blade moments.

Type of change

• Bugfix (non-breaking change which fixes my issue 2P IPC yaw feedback is never updated (axisYawF_2P) #510 )

Examples/Testing

Built baseline and corrected controller DLLs with GNU Fortran 13.2.0 and ran four
OpenFAST 5.0.0 simulations of the bundled NREL 5MW onshore model: proportional-only
and integral-only 2P IPC, each before and after the one-line correction. All runs
complete 60 seconds. The baseline's 2P yaw feedback/output remain zero despite
nonzero moments; the correction restores feedback and changes actual blade pitch.
