feat: control the 4O3A Tuner Genius XL directly over TCP (port 9010)

New internal/tunergenius client speaking the same "Genius Series" text API
as the Antenna Genius / PowerGenius XL: banner on connect (with optional
"AUTH" for remote access), "C<seq>|<cmd>\n" commands, "R<seq>|<code>|<msg>"
replies and the "S<seq>|status k=v …" snapshot; async "M|<msg>" info lines
are consumed inline. Polls status ~1.5s and exposes SWR (return-loss dB
converted to a VSWR ratio), forward power (dBm→W), and the operate/bypass/
tuning/active-channel state. Actions: autotune, global bypass, operate/standby.

Controlled directly (not via the radio) so OpsLog uses only one of the box's
four connection slots, per the device's protocol doc.

Wiring:
- app.go: tunergenius.* settings keys, Get/Save/start, GetTunerGeniusStatus,
  TunerGeniusAutotune/SetBypass/SetOperate; started in the background at launch.
- Settings → Tuner Genius panel (enable + IP + optional remote code).
- Docked TunerGeniusPanel widget (SWR/power readouts + Tune/Bypass/Operate),
  top-bar toggle, shown when enabled — mirrors the Antenna Genius widget.
- i18n EN/FR (sec.tunergenius, tg2.*, tgp.*).

Command verbs (operate/bypass/autotune/status/auth) come straight from the
4O3A "Tuner Genius XL — Protocol Description"; UNTESTED on hardware.
