feat: Add type definitions for configuration and service management

- Introduced `types.ts` to define interfaces for configuration, service instances, and request context.
- Implemented performance benchmarks for configuration parsing, Swagger spec generation, JWT token creation, and service response times in `bench.ts`.
- Created end-to-end tests for calculator and hello services, including admin endpoint authentication checks in `api_test.ts`.
- Developed integration tests for NanoEdgeRT startup and service request handling in `nanoedge_test.ts`.
- Added utility functions for testing in `test_utils.ts`, including server creation and JSON response assertions.
- Implemented unit tests for authentication middleware, configuration loading and saving, service manager functionality, and Swagger spec generation.
- Removed outdated worker test files that were no longer needed.
