Roman/feature/eliminate env files properties

[eightspokes]

This PR migrates the NGAFID application from environment variable-based configuration to a unified properties-based configuration system.

It consolidates all configuration into a single ngafid.properties file, eliminates scattered config files, and implements automatic Docker environment detection for deployment across development and production environments.

The org.ngafid.core.Config file serves as a bridge between properties file and the Java code (consumer).

Add your repository path and Azure Map keys to the properties file.
ngafid2.0/ngafid-core/src/main/resources/ngafid.properties

⚠️ SENSITIVE: Replace with your actual Azure Maps API key - DO NOT COMMIT REAL KEYS
ngafid.azure.maps.key= YOUR_KEY

⚠️ USER-SPECIFIC: Change this to your local path - DO NOT COMMIT YOUR ACTUAL PATH
ngafid.repo.path=PATH/ngafid2.0/

To add new property:

1. Add a property to the property file:

ngafid.debug.logging.enabled=false

2. Use the property in code:

import org.ngafid.core.Config;
boolean debugEnabled = Config.getBooleanProperty("ngafid.debug.logging.enabled");
