This PR removes the `compass_model` subproject and moves each data model
class to the respective `app` or `server` project.
Although this leads to code duplication, this is a more realistic
implementation where clients and servers have their own respective data
model class implementations.
The model classes for the server are located in `server/lib/model`.
Model classes for the app are located in two places:
- API-only model: `app/lib/data/services/api/model`.
- Domain model: `app/lib/domain/model`.
In general, models located under the domain are used across the app,
while the API-only models are only used for interacting with the API
client.
Tests have been updated.
