Fix synthesis blockers in 9 RTL files for Vivado compatibility
Guard all $display/$error/$time calls with ifdef SIMULATION in:
- chirp_memory_loader_param.v (initial + always block debug prints)
- cic_decimator_4x_enhanced.v (5 saturation/overflow displays + monitor block)
- ddc_400m.v (FIR/baseband debug monitor block)
- fft_1024_inverse.v (IFFT config debug block)
- matched_filter_multi_segment.v (16 state machine displays + monitor)
- nco_400m_enhanced.v (initial block debug print)
- radar_receiver_final.v (frame/chirp counter displays)
Replace SystemVerilog constructs with Verilog-2001:
- usb_data_interface.v (typedef enum -> localparam + reg)
- usb_packet_analyzer.v (typedef enum -> localparam, output reg -> wire)

Fix 6 RTL bugs in FPGA signal processing chain
- nco_400m_enhanced.v: Correct sine LUT values (3.7x quadrature error)
- ddc_400m.v: Fix wire forward-declaration (Verilog-2001 compliance)
- plfm_chirp_controller.v: Remove multi-driven chirp_counter (critical)
- radar_system_top.v: Fix CFAR wire-as-reg, connect chirp_counter to receiver
- radar_receiver_final.v: Promote chirp_counter to input port
All fixes verified with Icarus Verilog 13.0 testbenches (144/144 tests pass).
