fix: start lifecycle manager in web dashboard to update session status

The dashboard was permanently showing all sessions as "spawning" because
the lifecycle manager was never started. The lifecycle manager is the
component that polls sessions and detects state transitions (spawning →
working → pr_open → etc.), updating the metadata files accordingly.

This change initializes and starts the lifecycle manager when the web
services are created, enabling automatic session status updates.

Closes #79
