Fix all 10 CDC bugs from report_cdc audit, add overflow guard in range_bin_decimator

CDC fixes across 6 RTL files based on post-implementation report_cdc analysis: - P0: sync stm32_mixers_enable and new_chirp_pulse to clk_120m via toggle CDC in radar_transmitter, add ft601 reset synchronizer and USB holding registers with proper edge detection in usb_data_interface - P1: add ASYNC_REG to edge_detector, convert new_chirp_frame to toggle CDC, fix USB valid edge detect to use fully-synced signal - P2: register Gray encoding in cdc_adc_to_processing source domain, sync ft601_txe and stm32_mixers_enable for status_reg in radar_system_top - Safety: add in_bin_count overflow guard in range_bin_decimator to prevent downstream BRAM corruption All 13 regression test suites pass (159 individual tests).
