[feat](trx-frontend-http): add APRS decoder plugin with sub-tab navigation

Replace server-side /frontends endpoint with client-side plugin system.
The Plugins tab now has Overview and APRS sub-tabs. The APRS plugin
decodes packets from RX audio using Bell 202 AFSK demodulation (1200
baud), AX.25 frame decoding with NRZI/HDLC, and CRC-16-CCITT
validation. Decoded packets are displayed in a scrolling log.
