/**
 * TEST SKETCH 4.3 - DisplayManager Verifikation (angepasstes Layout)
 *
 * Modul-Aufteilung:
 *   Modul 0       : WiFi-Fehler-Indikator  (showWifiError)
 *   Module 1-3    : Laserzeit in ganzen Minuten, 3-stellig rechtsbuendig
 *   Modul 4       : MQTT-Fehler-Indikator  (showMqttError)
 *   Module 5-7    : Countdown-Sekunden / Idle / Status, 3-stellig rechtsbuendig
 *
 * Testet:
 *   1. Alle LEDs EIN/AUS (Modul-Check)
 *   2. WiFi-Fehler EIN/AUS (Modul 0)
 *   3. MQTT-Fehler EIN/AUS (Modul 4)
 *   4. showLaserTime() Grenzwerte: ganze Minuten, Module 1-3
 *   5. showCountdown() Grenzwerte: Module 5-7
 *   6. showIdle()
 *   7. showStatus() mit 3-Zeichen-Strings
 *   8. Kombinations-Test: WiFi+MQTT Fehler gleichzeitig mit Laserzeit+Countdown
 *   9. Realistischer Loop
 *
 * Flash:   pio run -e test-display-mgr --target upload
 * Monitor: pio device monitor -e test-display-mgr
