ci: Backend-e2e als eigener Workflow mit Postgres-Service

backend-e2e.yml läuft bei Änderungen unter ApiCore-Backend/ gegen einen
Wegwerf-Postgres 18.6 (per Digest), mit frisch erzeugten JWT-Secrets
und SKIP_EXTERNAL=1 für den Wetter-Test gegen die echte API. Der
Herdentest prüft globalen Zustand, den parallele Suites verändern; er
wiederholt die herdenabhängigen Fälle bis zu dreimal aus einem
zurückgesetzten Zustand. Lokal 3 volle parallele Läufe grün
(103 Suites, 1073 Tests).
