Improve zones.json for deployment

Fixes #43

Embed `zones.json` as a resource and modify code to read it.

* **Api.csproj**
  - Add `zones.json` as an embedded resource.

* **NwsManager.cs**
  - Modify `GetZonesAsync` method to read `zones.json` as an embedded resource instead of from the `wwwroot` folder.
  - Remove the `webHostEnvironment` parameter from the `NwsManager` constructor.
