Build-blocking fixes surfaced by gpu-server synth: 1. radar_system_top_50t.v wrapper was missing adc_or_p/n ports and the u_core instantiation left them unconnected. Every XDC line in the 50T anchor block (PACKAGE_PIN M6/N6, IOSTANDARD, DIFF_TERM, set_input_delay) therefore matched no ports and emitted CRITICAL WARNINGs, leaving the overrange pin effectively tied off. Added the two inputs and wired them through to the core. 2. adc_clk_mmcm.xdc used foreach / unset — Vivado's XDC parser only accepts a restricted Tcl subset and rejected them as [Designutils 20-1307]. Moved the clk_mmcm_out0 ↔ USB-clock false paths into each board XDC (ft_clkout for 50T, ft601_clk_in for 200T) where the clock name is already known.
