HTTP API / WebSockets

[ConnorC432]

Planning to implement a completely optional HTTP API / WebSocket interface to allow the application to be controlled remotely. This removes the need to use an RDP server to interact with the desktop application, making it more practical to control from other devices on the same network.

This PR isn't ready for merge yet, so it will remain as a draft for now.

Still need to:

• Complete API functionality by adding all necessary routes
• Send logs from the Output Window over websocket text messages

Related features that can come later:

• Add a headless mode to run only the API
• Determine if websocket connections can be changed to a http upgrade to reduce it to a single bound port only
• Evaluate using Qt's SSL to improve security - (exposing the API to the internet is not an intended use so this isn't entirely necessary)
