* [ee] feat: add OTel metrics support
Add OpenTelemetry metrics export for Windmill operational metrics.
When the OTel metrics toggle is enabled in instance settings (EE),
Windmill exports 16 metrics to any OTLP-compatible collector, letting
users observe queue depths, worker execution, DB pool state, and health
without a separate Prometheus setup.
Changes:
- otel_oss.rs: no-op stubs for OSS builds
- monitor.rs: queue count/running count gauges, zombie counters, DB pool
monitoring (shared single DB query and loop with Prometheus)
- worker.rs: execution count/duration, worker busy, pull duration
- jobs.rs: queue push/delete/pull counters
- health.rs: DB latency gauge
- main.rs: call monitor_pool_otel unconditionally
- InstanceSetting.svelte: enable metrics toggle for EE licenses

* chore: update ee-repo-ref.txt for OTel metrics
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add worker_started, worker_uptime, health_status, health_db_unresponsive OTel metrics
Wire up 5 additional metrics to reach parity with Prometheus:
- worker_execution_failed: wired in add_completed_job_error (was defined but unused)
- worker.started: incremented on worker startup
- worker.uptime: recorded each loop iteration
- health.status: phase gauge (healthy/degraded/unhealthy)
- health.db_unresponsive: flag (0/1)

* chore: update ee-repo-ref to fbe68e4aa621e30378995cfd328a6ccf74176614
This commit updates the EE repository reference after PR #469 was merged in windmill-ee-private.
Previous ee-repo-ref: 6fa1881aafdfb60f4abf11a37f01f6fedaecb3ec
New ee-repo-ref: fbe68e4aa621e30378995cfd328a6ccf74176614
Automated by sync-ee-ref workflow.
* fix: remove duplicate cfg attr and duplicate OTel pool reporting
- Remove duplicate #[cfg(feature = "prometheus")] on monitor_pool
- Remove OTel block from monitor_pool; monitor_pool_otel is the sole
OTel reporter, eliminating duplicate windmill.db.pool.* metrics in
EE builds
- Simplify monitor_pool back to its original Prometheus-only structure
