[FA-32] Implement Dockerfile

[scott-clare1]

This PR adds a Dockerfile for the server to make running the server more consistent.

What

A Dockerfile to run the server.

An entry point for consistently running the server, i.e., it is now runnable as a command line script, e.g., uv run agent-uno

Why

To remove any issues different devices or missing installations and to make it more of a production solution.

How

With a Dockerfile.

Extra

I had to refactor the project so that agent_uno now sits under src this is needed for identifying the project as a command line script.

If new dependencies are introduced to the project, please list them here:

• click a command line tool.

Checklist

Please ensure you have done the following:

• I have updated the documentation if required.
• I have added tests which cover my changes.

Type of change

Make sure to update label on right hand panel.

MacOS tests

To trigger the CI to run on a macOS backed workflow, add the macos-ci-test label to the pull request (PR).

Our advice is to only run this workflow when testing the compatability between operating systems for a change that you've made, e.g., adding a new dependency to the virtual environment.

Note: This can take up to 5 minutes to run. This workflow costs x10 more than a Linux-based workflow, use at discretion.
