Remove JsonInjector class

[horgh]

This was not doing much given we always passed IP and network as null. In the past, when we used Jackson for MMDB deserialization, this was more extensively used.

Pull Request Overview

This PR removes the JsonInjector class and simplifies Jackson deserialization by removing @JacksonInject annotations that were always passing null values. The change eliminates unnecessary dependency injection complexity since IP address and network parameters were consistently null.

• Replaces JsonInjector with standard Jackson InjectableValues.Std for locales injection
• Removes @JacksonInject annotations from constructor parameters across all response models
• Deletes the JsonInjector class entirely
