### Context
For calendar and message sync job health monitoring, we used to
increment a counter in redis cache which could lead to concurrency
issue.
### Solution
- Update to a set structure in place of counter + use sAdd redis method
which is atomic
- Each minute another counter was incremented on a new cache key ->
Update to a 15s window
- Remove ONGOING status not needed. We only need status at job end (or
fail).
### Potential improvements
- Check for cache key existence before fetching data to avoid useless
call to redis ?

# Health Monitoring for Self-Hosted Instances
This PR implements basic health monitoring for self-hosted instances in
the admin panel.
## Service Status Checks
We're adding real-time health checks for:
- Redis Connection
- Database Connection
- Worker Status
- Message Sync Status
## Existing Functionality
We already have message sync and captcha counters that store aggregated
metrics in cache within a configurable time window (default: 5 minutes).
## New Endpoints
1. `/healthz` - Basic server health check for Kubernetes pod monitoring
2. `/healthz/{serviceName}` - Individual service health checks (returns
200 if healthy)
3. `/metricsz/{metricName}` - Time-windowed metrics (message sync,
captcha)
4. GraphQL resolver in admin panel for UI consumption
All endpoints use the same underlying service, with different
presentation layers for infrastructure and UI needs.

Context :
We want to implement some counters to monitor server health. First
counters will track : messageChannel sync status during job execution
and invalid captcha.
How :
Counters are stored in cache and grouped by one-minute windows.
Controllers are created for each metric, aggregating counter over a
five-minutes window.
Endpoints are public and will be queried by Prometheus.
