feat(gui): add FT601Connection class, USB interface selection in V65/V7

Browse Source 
- Add FT601Connection in radar_protocol.py using ftd3xx library with
  proper setChipConfiguration re-enumeration handling (close, wait 2s,
  re-open) and 4-byte write alignment
- Add USB Interface dropdown to V65 Tk GUI (FT2232H default, FT601 option)
- Add USB Interface combo to V7 PyQt dashboard with Live/File mode toggle
- Fix mock frame_start bit 7 in both FT2232H and FT601 connections
- Use FPGA range data from USB packets instead of recomputing in Python
- Export FT601Connection from v7/hardware.py and v7/__init__.py
- Add 7 FT601Connection tests (91 total in test_GUI_V65_Tk.py)

- FT2232HConnection for production board (FT2232H USB 2.0)
- FT601Connection for premium board (FT601 USB 3.0) — selectable from GUI
- Unified replay via SoftwareFPGA + ReplayEngine + ReplayWorker
- Mock mode (FT2232HConnection(mock=True)) for development
The old STM32 magic-packet start flow has been removed. FPGA registers
are controlled directly via 4-byte {opcode, addr, value_hi, value_lo}
commands sent over FT2232H.
