What happened?

Version: 0.7.17
OS: Linux Mint
Radio: FLEX-6400

Describe the bug:
When WSJT-X sends a set_freq (F) command via rigctld (localhost:4532),
AetherSDR shifts the panadapter center frequency instead of tuning the
slice to the new frequency. The waterfall/slice stays on the original
frequency (e.g. 30m FT8 at 10.136 MHz) while the panadapter center moves
to the new frequency.

Steps to reproduce:

1. Connect WSJT-X to AetherSDR rigctld (Hamlib NET rigctl, localhost:4532)
2. Change band in WSJT-X (e.g. from 30m to 20m)
3. Observe: panadapter center moves to 14 MHz, but slice and waterfall
   remain on 10 MHz

Workaround:
Change band manually in AetherSDR, then let WSJT-X only control the
exact FT8 frequency within the band.

What did you expect?

Expected behavior:
set_freq should call slice tune <index> <freq> on the active slice,
not display pan set_center.
