chore(tools): qconnex-Migrationswerkzeug und HA-Integration ins Repo

qconnex-listen/ (OTA-Falle: AP + DHCP + Range-Server, Onboarding-Client) und
ha-integration/ (Home-Assistant-custom_component ninlight) waren seit der
Erfindung nur auf diesem Rechner. Bilder, Request-Log, hostapd-Log und PIDs
ueber .gitignore draussen - die Images sind generierbar, sobald die
Signierschluessel erreichbar sind. otaserve.py bildet jetzt auch die
Montana-Black-Produkt-ID auf ledshield_rgb ab.
