G1000: manual-accurate radios, baro units, declutter, minimums, OBS, audio panel

Aligned to the official X-Plane 1000 manual:
- NAV radio: active RIGHT / standby LEFT (boxed) per S.12 (COM already correct)
- ALT UNIT softkey (IN / HPA) in the PFD submenu, baro readout converts (S.20)
- DCLTR cycles 3 levels (land / +NDB / flight-plan only) with DCLTR-n label (S.56)
- TOPO and TERRAIN are now independent toggles (relief vs awareness overlay) (S.57)
- Barometric MINIMUMS: BARO MIN bug + readout on the altimeter, amber "MINIMUMS"
  annunciation at/below the decision altitude; set via TMR/REF (lifted to App)
- OBS mode: HSI course follows the CRS knob (magenta "OBS"), sequencing suspended
- New Audio Panel tab (COM mic/receive, MKR/DME/ADF, intercom, Display Backup) (S.91)
