web: Migrate web runner to REST API

This pull request updates the web runner to remove its hard dependency on a 
direct database connection. Instead, it now communicates via the REST API.

* Add endpoint for scheduling simulation jobs
* Create simple API client for web runner
* Remove direct database connection from web runner
* Improve validation of API input/output data
