feat(tscm): add custom frequency range option to RF sweep

Browse Source 
Adds a "Custom Range" sweep type that lets users specify start/end MHz
instead of using a fixed preset. Useful in dense RF environments where
a full or standard sweep returns too many signals and causes slowdown.

UI shows start/end MHz inputs when "Custom Range" is selected. Range is
validated (0 < start < end ≤ 6000 MHz) before the sweep starts.
Backend threads the ranges through to _scan_rf_signals(), which already
supports arbitrary frequency bands.

Closes #172
