chore: create network order controller

[salimtb]

Explanation

The NetworkOrderController is a core implementation of network ordering functionality that was previously only available in the extension. This PR moves and expands this functionality from the extension's NetworkOrder controller to core, enabling network ordering features across both extension and mobile platforms. It also renames it to NetworkOrderController to more accurately represent what it does. Maybe in the future this can be expanded to include other UX enhancements that don't need to be tightly coupled with the NetworkController

Key motivations for this change:

1. Platform Parity: Network ordering was previously only implemented in the extension via NetworkOrder controller, leaving mobile without this functionality. Moving this to core will unlock the ability to have this feature built on mobile.

2. Code Quality Improvements: The move to core has provided an opportunity to:

   • Improve test coverage of the existing network ordering logic

The controller now handles three key aspects:

• Network ordering (preserved from extension implementation)

• Moves functionality from NetworkOrder controller in extension to core
