Jason 166464e877 fix(fpga): PR-O.8.1 — drop stale BFP-era ports, fix xsim include path ...

Wrapper xfft_2048.v had m_axis_data_tuser and m_axis_status_{tdata,tvalid,
tready} hooked up to the IP, but the regenerated xfft_2048_ip in scaled
mode + Pipelined Streaming + 1 channel + no XK_INDEX/OVFLO doesn't expose
those ports. xelab errored "cannot find port" on all four. Removed.

run_xfft_xsim.sh missed -i "$PROJ_ROOT" so xvlog couldn't resolve
`include "radar_params.vh"` from inside tb/. Fixed.

gen_xfft_2048_ip.tcl header comment described the old Burst I/O 11-stage
schedule; updated to PG109 Pipelined Streaming pair-grouped layout that
matches the actual SCALE_SCH = 12'hAA9 we now drive.

Verified: tb_xfft_2048_xsim 5/5 PASS on real LogiCORE FFT v9.1 IP under
Vivado 2025.2 xsim — DC peak at bin 0, impulse flat spectrum, tone at
bin 128. Closes T-10 (FFT-block synth-mode validation).
