fix: Add missing SSTV mode specs for HF decoding (PD90/PD160/PD240/ScottieDX)

Browse Source 
VIS detection recognized these modes but ALL_MODES had no decoder specs,
causing silent decode failures on common HF frequencies like 14.230 MHz.
Also emit a user-visible SSE event when an unsupported VIS code is detected.
