Subject: PMIM-1 hardware support: UDP, IIXDR, inclinometer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Transport:
- NmeaStreamManager supports TCP and UDP modes
- NmeaConnectionPrefs replaces hardcoded 192.168.1.1:10110; defaults
  to UDP/10110 matching PMIM-1 spec (ESP32 AP at 192.168.4.1)
- LocationService reads prefs via startNmeaFromPrefs()

Parsing:
- NmeaParser.parseXdr() handles $IIXDR attitude (HEEL/PTCH in degrees)
  and baro (pressure in bar → hPa, air temp °C)
- New AttitudeData and NmeaBaroData sensor types

UI:
- Heel + pitch row in instrument sheet (hidden until data arrives)
- InclinometerView: canvas circle with rotating waterline (heel) and
  displaced dot (pitch), colorPrimary-tinted, respects night mode
- Inclinometer overlay top-left of map, appears on first attitude packet
- NMEA baro overrides device sensor reading when available
