This commit introduces comprehensive guidelines for managing development and production environments, addressing the user's strategic questions regarding workflow, webhook handling, and secure email sending.
- **Teil 4: Entwicklungs- vs. Produktions-Workflow:** Documents the 'separated worlds' approach for development on Synology and production on the Wackler VM, detailing configuration separation, webhook handling, and safe email testing.
- **Teil 5: Alternative - Single-Host-Setup:** Provides a robust strategy for running both development and production environments on a single VM, emphasizing directory structure, port conflict resolution, and guaranteed database isolation via Docker volumes.
These additions clarify the operational guidelines for maintaining system stability and data integrity post-migration.
