fix: upgrade all Dockerfiles to node:24-alpine, fix portal build errors

- Update all 12 Dockerfiles from node:18/20/22 to node:24-alpine
- Fix caproverforge portal: remove event handlers from Server Component
- Fix repoforge/caproverforge portals: ensure public/ dir exists in builder
- Fix packagerepo Dockerfile: node:18 → node:24 (Next.js 16 requires >=20)
- Fix DBAL frontend port conflict: 3009 → 3015 (3009 in use by external container)
