🎉 feat(ci): setup Gitea Actions riutilizzabili cross-repo

- Aggiunti 6 workflow condivisi in .gitea/workflows/ con trigger workflow_call
- Implementati: quality-gates, npm-publish, docker-release, auto-release, dependency-check, branch-cleanup
- Aggiunti esempi consumer per microservizio e libreria-npm (ci, release, maintenance)
- Allineato npm run lint:check su tutti i workflow
- Corretti GITEA_TOKEN, gitea.* context, GITHUB_REF/GITHUB_OUTPUT per compatibilità Gitea
- Rimosso needs: tra job reusable (Gitea bug #31900), path uses: con .gitea/workflows/

Fixes #1 @1d
