New /health-check endpoint verifies:
- Gitea release integrity (manifest version matches tag)
- Duplicate ZIP assets in releases
- EspoCRM API reachability per customer
- Extension load status on each instance
- Stale deployments (logged ok but version not updated)
New n8n workflow runs at 07:00 & 19:00, combines health check
with drift sync, and posts combined report to Mattermost.
