[feat](trx-frontend-http): add auto tone and WPM detection to CW decoder

Browse Source 
Add Auto checkboxes (checked by default) next to WPM and Tone inputs.
Auto Tone uses a multi-bin Goertzel scan across 300-1200 Hz with
stability tracking. Auto WPM collects on-durations in a rolling buffer
and uses k-means-style clustering to separate dits from dahs.
Unchecking Auto allows manual control.
