espid2sensor in Hauptstack aufnehmen, verschachteltes Git-Repo aufgeloest

espid2sensor lief bisher nur per eigenem Dev-Compose mit isolierter
Wegwerf-Mongo. Jetzt Teil von noisesensors/docker-compose.yml, Port 3004,
Zugriff auf die dort laufende mongodb-Instanz (sensor_data). DEV_AUTO_LOGIN
explizit aus, SESSION_SECRET ueber neue Env-Variable statt Code-Default.

Dockerfile_esp2sensor an das Muster der anderen Services angeglichen
(node:22-alpine, /opt/app, npm ci, tzdata/Europe-Berlin, deluser node).

espid2sensor/.git entfernt (war eigenes verschachteltes Repo) und der
komplette Verzeichnisinhalt ins laermsensor-stack-Repo uebernommen.
