Remove inline root, health, and echo routes

Delete the local implementations of '/', '/health', and '/echo' from app/api/routes.py. These handlers were redundant after including root_router, health_router, and echo_router at the top of the file; removing them centralizes route definitions and eliminates the duplicate DB cursor and local Echo request/response logic.
