Hermes c5a09833c9 FIX-NETATMO-05: ACeP Native-Farben + bessere Spalten-Verhaeltnisse
* Farben auf ACeP 7-Farben-Palette gemappt: BLACK, WHITE, GREEN, BLUE, RED, YELLOW, ORANGE
  (PIL.quantize dithert sonst alles in matschige Mischfarben)
* Background PAPER_BG = (255,255,255) echtes Weiss statt warm-creme
* Spalten-Verhaeltnis neu: Indoor 32% (mehr Platz fuer 5 Sensoren),
  Aussen 28%, Mitte 18%, Forecast 22%
* Big-Temp candidates von [150,130,110,95] auf [120,100,85,72,60] reduziert
* FAINT und INK_LIGHT als BLACK definiert (Grautöne ergeben Mischpixel)
* Funktioniert mit echten Daten: zeigt 5 Indoor-Sensoren + alle Aussensensoren

"""Netatmo Weather Station Plugin — WarmNews 4x4 Layout.
Zeigt Live-Daten einer Netatmo Wetterstation mit allen Sensoren:
- 1x NAMain + bis zu 4x NAModule4 Indoor-Sensoren
- 1x NAModule1 Outdoor
- 1x NAModule2 Wind
- 1x NAModule3 Regen
Layout (4x4 = 800x480):
Spalte 1: Aussen (Temp gross + MIN/MAX/LUFT/DRUCK + 12h-Verlauf)
Spalte 2: Wind + Regen (gestapelt, mit 1h/24h-Bars)
Spalte 3: Indoor (5 Sensoren prominent: Tag/Name/Temp/CO2/Batt)
Spalte 4: Forecast (3 Tage)
