serversdwn 5ee6f5eb28 feat: Enhance dashboard with filtering options and sync SLM status
- Added a new filtering system to the dashboard for device types and statuses.
- Implemented asynchronous SLM status synchronization to update the Emitter table.
- Updated the status snapshot endpoint to sync SLM status before generating the snapshot.
- Refactored the dashboard HTML to include filter controls and JavaScript for managing filter state.
- Improved the unit detail page to handle modem associations and cascade updates to paired devices.
- Removed redundant code related to syncing start time for measuring devices.

"""
SLM Status Synchronization Service
Syncs SLM device status from SLMM backend to Terra-View's Emitter table.
This bridges SLMM's polling data with Terra-View's status snapshot system.
SLMM tracks device reachability via background polling. This service
fetches that data and creates/updates Emitter records so SLMs appear
correctly in the dashboard status snapshot.
