fix(socket-io): update import path for socket-server module

Fix import path from '../../socket-server' to '../socket-server'
to point to the TypeScript source file instead of the deleted
compiled file in the root.

Path resolution:
- From: src/lib/socket-io.ts
- Import: '../socket-server'
- Resolves to: src/socket-server.ts
