[Feature]: TypeScript-Based Testing Framework for DevKit Backend

### 🚀 The feature and your motivation

The Cardano DevKit requires a TypeScript-based testing framework that interacts with the DevKit backend to manage Yaci-DevKit instances. This framework should enable the creation of tests that can connect to a Yaci-DevKit, spin up a new DevKit instance with a config to top up addresses, and/or close a DevKit instance, e.g. in an afterAll function.

### Additional context

Blocked by #13

Review blocking issue #13 first, since this feature depends on it. Define the TypeScript testing framework around connecting to Yaci-DevKit, starting a configured DevKit instance that can top up addresses, and closing the instance for cleanup such as in an afterAll function. Done means these lifecycle operations are usable from tests.
