[feat](trx-rs): split VDES frontend and decoder path

Add a dedicated VDES plugin tab and live bar, stop reusing the AIS vessel UI, and serve a separate VDES frontend script. Rework the SDR backend so VDES receives a single 100 kHz IQ tap, then replace the fake AIS-clone decoder path with an early M.2092-1 oriented complex-baseband scaffold using burst detection, coarse pi/4-QPSK slicing, and TER-MCS-1.100 frame heuristics.
