rtl_fm stderr was sent to DEVNULL, hiding the actual failure reason
(rc=1). Now captured and surfaced in the error response. Also drains
rtl_fm stderr during normal operation to prevent pipe blocking.

Use -o - (stdout) instead of -o /dev/null for audio output, as
dsd-fme expects specific output targets. Remove -N flag which may
cause issues in headless mode. Add stderr capture on pipeline
failure for better error messages.

dsd-fme uses different protocol flags than classic dsd (e.g. -fs for
DMR instead of -fd, -f1 for P25 instead of -fp). Add -N flag to
disable ncurses terminal which is required when reading from stdin pipe.

Check for dsd-fme binary (common fork) before falling back to dsd.
Disable audio output with -o /dev/null to prevent PulseAudio
connection failures when running under sudo.
