Subject: [PATCH 10/19] Add configuration file and API endpoint

This commit adds a new configuration file, `index.ts`, which exports an object containing various configuration options for the application. It also adds a new API endpoint in the `index.ts` file, which responds with a simple message to indicate that the EchoVote API is running.
