feat: multiple amplifiers + SmartSDR v4 DSP filters

Multi-amp: Settings->Amplifier becomes a list (amps.json, legacy single-amp keys auto-migrate to entry #1); one client per enabled amp with per-id bindings (GetAmplifiers/SaveAmplifiers/GetAmpStatuses/AmpOperate/AmpPower/AmpPowerLevel/AmpFanMode); legacy a.pgxl/a.spe/a.acom point at the first enabled amp of each family. Amp cards in FlexPanel and Station Control gain a dropdown to pick the amp; the status bar shows one clickable chip per amp. Use case: two SPEs run in parallel.

Flex v4 DSP (8000/Aurora): NRL/ANFL (lms_nr/lms_anf), NRS (speex_nr), NRF (nrf) with level sliders, RNN (rnnoise) and ANFT on/off — keys per the FlexLib slice docs; the section only shows when the radio reports these keys (dsp_v4 flag), so 6000-series panels are unchanged.
