Add DMR digital voice, WebSDR, and listening post enhancements
- DMR/P25 digital voice decoder mode with DSD-FME integration - WebSDR mode with KiwiSDR audio proxy and websocket-client support - Listening post waterfall/spectrogram visualization and audio streaming - Dockerfile updates for mbelib and DSD-FME build dependencies - New tests for DMR, WebSDR, KiwiSDR, waterfall, and signal guess API - Chart.js date adapter for time-scale axes Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
