Make server listen address configurable via flags

Browse Source 
To improve the flexibility and configurability of the server, add a
`listen` flag to specify the server's listen address. This replaces
the hardcoded `localhost:3002` string.

This change addresses the need for configuring the server address
dynamically, facilitating easier deployment and testing.

Resolves: #8
