chore(network): point ApiConfig at PROD by default

Was on Environment.LOCAL — useful for local-against-127.0.0.1 dev but
means a release build off main hits a server the device can't reach.
Switch to Environment.PROD so the app talks to api.myhoneydue.com.
LOCAL/DEV are still one-line toggles in ApiConfig.kt for development.
