Fix XVTR/FM frequency, mode and step persistence

- Fix web spectrum scroll resetting freq to XVTR minimum (same root
  cause as desktop: hardcoded 60 MHz clamp; now delegates to server)
- Save/restore FM mode, NFM/WFM filter, squelch, CTCSS per XVTR slot
  and per HF band (CTCSSOn/ToneIdx added to TBandSettings; full state
  added to TXvtrEntry; ActivateXvtrBand restores all on slot switch)
- Fix UpdateFilterButtons always resetting NFM/WFM to default on
  mode restore; now preserves saved filter index
- Add FM Step tuning: panel with STEP toggle + 6.25/12.5/20/25 kHz
  selector (popup); mouse wheel uses selected step in FM mode;
  state saved per band and XVTR slot
