feat: add function to retrieve linked names for Ipsymcon variables

- Created a PowerShell script (update.ps1) for automating the process of pulling the latest repository changes, stopping, building, and starting the Docker Compose stack.
- Updated App.jsx to include new admin sections for alarms and integrations, added state management for runner jobs, and enhanced permission checks.
- Extended the API module (api.js) with new endpoints for managing integrations and runner jobs.
- Improved CSS styles for a more compact and responsive layout in the admin interface, focusing on source and datapoint cards.

 SE Local Trenddata ist eine webbasierte Trend-, Dashboard- und Quellenverwaltung fuer lokale Anlagen- und WAGO-Daten. Das Projekt besteht aus einem React-Frontend, einer Node.js/Express-API, MariaDB, Redis und einem Collector-Service fuer Protokollquellen wie Modbus TCP, OPC UA, BACnet IP und KNX IP.

 - Fuer vollstaendige Protokollintegration muessen je nach Feldbus noch Details wie Adressierung, Datentyp, Byteorder und Authentifizierung sauber projektspezifisch gepflegt werden.

+## Konfiguration und Sicherheit
+
+Vor dem ersten Start `.env.example` nach `.env` kopieren und mindestens `JWT_SECRET`, `ADMIN_PASSWORD` und `REDIS_PASSWORD` durch eigene lange Zufallswerte ersetzen. Die lokale `.env` wird nicht versioniert.
+
+Redis ist ausschließlich innerhalb des Docker-Netzwerks erreichbar und verlangt ein Passwort. Für Diagnosezwecke:
+
+```powershell
+docker compose exec redis redis-cli -a $env:REDIS_PASSWORD ping
+```
+
+Alle Dienste können vor einem Deployment statisch geprüft werden:
+
+```powershell
+npm --prefix api run check
+npm --prefix collector run check
+npm --prefix symcon-collector run check
+npm --prefix bacnet-collector run check
+npm --prefix runner run check
+npm --prefix web run check
