fix: align all range/carrier/velocity values to PLFM hardware + FPGA bug fixes

- Correct carrier from 10.525/10 GHz to 10.5 GHz (verified ADF4382 config)
- Correct range-per-bin from 4.8/5.6/781.25 m to 24.0 m (matched-filter)
- Correct velocity resolution from 1.484 to 2.67 m/s/bin (PRI-based)
- Correct processing rate from 4 MSPS to 100 MSPS (post-DDC)
- Correct max range from 307/5000/50000 m to 1536 m (64 bins x 24 m)
- Add WaveformConfig.pri_s field (167 us PRI for velocity calculation)
- Fix short chirp chirp_complete deadlock (Bug A)
- Remove dead short_chirp ports, rename long_chirp to ref_chirp (Bug B)
- Fix stale latency comment 2159 -> 3187 cycles (Bug C)
- Create radar_params.vh as single source of truth for FPGA parameters
- Lower RadarSettings.cpp map_size validation bound from 1000 to 100
- Add PLFM hardware constants to golden_reference.py
- Update all GUI versions, tests, and cross-layer contracts

All 244 tests passing (167 Python + 21 MCU + 29 cross-layer + 27 FPGA)
