refactor(infra): Restrukturierung Config-Ordner & Einführung von Docker-Profilen
Umfangreiches Refactoring der Projektkonfiguration zur klaren Trennung von Build-, Runtime- und Applikations-Logik. Änderungen im Detail: - Struktur: Neuorganisation des `config/` Verzeichnisses in logische Bereiche: - `config/docker`: Reine Infrastruktur-Configs (Postgres, Redis, Nginx, Monitoring). - `config/quality`: Statische Code-Analyse (Detekt, Lint). - `config/app`: Gemeinsame Spring-Boot-Konfigurationen. - Docker Compose: - Einführung von Profilen (`infra`, `backend`, `ops`, `gui`, `tools`) für gezieltes Starten von Teilbereichen. - Anpassung aller Volume-Pfade auf die neue Struktur. - Spring Boot Config: - Zentralisierung gemeinsamer Einstellungen (Datasource, Redis, JPA) in `config/app/base-application.yml`. - Parametrisierung der Hosts für nahtlosen Wechsel zwischen Docker und Localhost. - Bereinigung der service-spezifischen `application.yaml` Dateien (z.B. Ping-Service). - Cleanup: Entfernen redundanter "Ghost-Files" (`versions.toml`, `central.toml`, `config/.env`), um eine echte Single Source of Truth (SSoT) zu gewährleisten.
