left4me: reuse nginx bundle's auto-monitoring via check_path

Browse source 
bundles/nginx/metadata.py:91-104 already creates a monitoring/services
entry per nginx/vhost using the vhost's check_protocol/check_path. Set
check_path: '/health' on the left4me vhost so the auto-check hits the
Flask health endpoint, drop the explicit monitoring/services/left4me-web
block from this reactor.

Net effect: same curl command lands in monitoring as before, but the
service name is now 'left4.me' (the hostname, per the nginx reactor's
naming convention) instead of 'left4me-web'.
