Jason af64b0952e fix(fpga): PR-O.8 — cfg_tdata 24->16 for Pipelined Streaming I/O

PR-O in 8541443 packed cfg_tdata using PG109 Burst I/O semantics (22-bit
SCALE_SCH, 24-bit total). The xfft_2048 IP we instantiate is Pipelined
Streaming I/O — that arch has SCALE_SCH width = 2*ceil(NFFT_MAX/2) = 12
bits, cfg_tdata = 16 bits. Mismatch surfaced when the Vivado-regenerated
.xci reported C_S_AXIS_CONFIG_TDATA_WIDTH=16. Realigns wrappers + TBs.

Total /N scaling preserved: 22'h155555 (/N as 11 stages of >>1) becomes
12'hAA9 (stage 1 alone >>1 + stages 2-11 grouped as 5 pairs of >>2 each).
Iverilog fft_engine.v fallback unchanged — applies fixed >>>1 per stage.

Verified: tb_fft_engine_axi_bridge 4/4, tb_matched_filter_processing_chain
40/40. Vivado .dcp / .veo regenerated from .xci; gitignored as usual.
