feat(09-01): add Group field to FreqConfig and rebalance ClassFreqConfigs

Browse Source 
- Add Group string field to FreqConfig struct (GRP-04)
- Add frequency allocation table comment (32 slots, 65-2449 Hz, FREQ-03)
- Rebalance all 14 ClassFreqConfigs entries to major-second ladder (FREQ-01)
- Infrastructure band (Triangle, 65-133 Hz): ICMP/NTP/DHCP/DNS
- Web band (Sawtooth, 150-169 Hz): HTTPS/HTTP
- Mail band (Triangle, 214 Hz): SMTP
- Remote Access band (Square, 343 Hz): SSH
- Unknown band (Custom, 771-1375 Hz): Unknown1-4, OtherTCP, OtherUDP
- Remove stale NumLayers and GainPerLayer constants (Phase 8 cleanup)
- Non-Unknown entries use WaveformPresetHarmonics; Unknown retain hand-tuned {1,1.0},{2,0.8},{3,0.4}
