CRITICAL FIX: Separate RQLite and LibP2P ports to prevent service startup failures
Changes:
- LibP2P now uses port 4000 (was conflicting with RQLite on 4001)
- RQLite continues to use port 4001 for HTTP API
- RQLite Raft uses port 4002
- Updated bootstrap peer configurations to use port 4000
- Updated install script port configurations
- Fixed firewall configuration to allow correct ports
This resolves the 'bind: address already in use' error that was preventing
the debros-node service from starting properly.
