+feat: complete migration from DevicePollerWorker to CheckExecutorWorker
+  - Removed all DevicePollerWorker scheduling from device lifecycle
+  - Checks now automatically scheduled via Monitoring.schedule_check when created
+  - Discovery creates checks and schedules them in a single transaction
+  - Added Monitoring.stop_device_checks/1 to cancel all check jobs for a device
+  - Added Monitoring.disable_device_checks/1 to disable checks when SNMP is turned off
+  - Device creation: removed polling start (checks created during discovery)
+  - Device deletion: replaced DevicePollerWorker.stop_polling with stop_device_checks
+  - SNMP enable/disable: replaced polling control with check enable/disable
+  - DevicePollerWorker no longer referenced in devices.ex (fully migrated)
+  - System now runs single unified polling mechanism via CheckExecutorWorker
+  - Files: lib/towerops/devices.ex, lib/towerops/monitoring.ex,
+    lib/towerops/snmp/discovery.ex
