Bardioc26 261a6294cb Desktop app dynamic config of API Port (#40 )

* added dynamic configuration of Port in Desktop app
* added dynamic configuration of API_URL to docker deployments.

Now it works with editing only .env file.

Desktop Runtime Configuration

The BaMoRT desktop app now uses runtime configuration for the API port, meaning you can change the port in the .env file without rebuilding the app.

How It Works

Backend (Go)

desktop/main.go: The App.GetAPIBaseURL() method reads the configured port from config.Cfg and returns the full API URL
This method is bound to the frontend via Wails, making it callable from JavaScript

Frontend (Vue/JS)

frontend/src/utils/config.js: Detects if running in Wails and calls the Go backend to get the API URL at runtime
frontend/src/utils/api.js: Uses the dynamic config instead of a hardcoded VITE_API_URL
The API URL is cached after first retrieval for performance

Build Process

frontend/package.json: The build:desktop script no longer hardcodes VITE_API_URL
The frontend bundle is now port-agnostic

Usage

Change the API Port

Edit desktop/.env:

API_PORT=8185  # Change to any port you want

Run the app - no rebuild needed!
```
./desktop/build/bin/bamort
```

The frontend will automatically connect to the configured port.

Environment Detection

The config system automatically detects the environment:

Desktop (Wails): Calls window.go.main.App.GetAPIBaseURL() to get the URL from Go backend
Web (Development): Uses import.meta.env.VITE_API_URL from Vite
Web (Production): Defaults to https://bamort-api.trokan.de

Fallback Behavior

If the desktop app can't reach the Go backend (shouldn't happen), it falls back to http://localhost:8185.

Benefits

✅ Change API port without rebuilding
✅ Faster iteration during development
✅ Same binary works with different configurations
✅ Cleaner separation of config from code

Technical Details

Request Flow:

Frontend makes API request
Axios interceptor checks if baseURL is set
If not set, calls getAPIBaseURL() from config.js
Config.js detects Wails environment via window.go
Calls Go backend's GetAPIBaseURL() method
Caches the result for subsequent requests
Request proceeds with correct baseURL
