The bundled PostgreSQL server is 18.x, but the client tools shipped in the images lagged behind (Debian: 17, Alpine/nginx: 16). pg_dump refuses to dump a server newer than itself, so `manage.py dbbackup` failed with "aborting because of server version mismatch". Align the client to the server (v18): - Alpine images: bump base to alpine3.23 and use postgresql18-client (18 is not available in the alpine3.22 repos). - Debian image: add the PostgreSQL APT (PGDG) repository and install postgresql-client-18 (Debian trixie only ships v17). Fixes DefectDojo#15301

Summary
manage.pyscript is not working because of server version mismatch #15301:./manage.py dbbackupfails withpg_dump: error: aborting because of server version mismatchbecause the PostgreSQL client tools in the images are older than the bundled PostgreSQL 18 server, andpg_dumprefuses to dump a server newer than itself.postgresql-clienton trixie), and the Alpine/nginx images shipped v16 (postgresql16-client).Dockerfile.django-alpine,Dockerfile.nginx-alpine): bump the base image toalpine3.23and installpostgresql18-client. The v18 client is not available in thealpine3.22package repos, so the base bump is required. The nginx build-stage base is kept identical to the django build stage to preserve Docker layer caching.Dockerfile.django-debian): Debian trixie only shipspostgresql-client-17, so add the PostgreSQL APT (PGDG) repository and installpostgresql-client-18in the release stage.
