CRITICAL FIXES:
- Fix unsafe pattern matching in SNMP discovery that would crash on timeout
- Changed {:ok, _} = ... to proper case statements with error handling
- Extracted safe_discover/3 helper to reduce cyclomatic complexity
- Added fallback to empty lists and warning logging for timeouts
- Affects: discover_vlans, discover_ip_addresses, discover_processors, discover_storage
MEMORY LEAK FIXES (JS Hooks):
- GlobalSearchTrigger: Added destroyed() cleanup for click listener
- SidebarCollapse: Added destroyed() cleanup for click listener
- ThemeSelector: Added destroyed() cleanup for phx:set-theme window listener
- NetworkMap: Added destroyed() cleanup for 3 button listeners (zoom in/out/fit)
- All hooks now properly store handler references and remove listeners on unmount
LIVEVIEW FIXES:
- Added phx-update="ignore" to 5 SensorChart hooks to prevent chart re-initialization
- Added catch-all handle_info(_msg, socket) to 5 LiveViews to prevent crashes on unexpected messages
- device_live/show.ex, device_live/index.ex, alert_live/index.ex, activity_feed_live.ex, agent_live/index.ex
N+1 QUERY FIXES:
- Created Gaiia.get_site_subscriber_summaries/1 batch function
- Refactored alert_live and device_live to use batch query instead of looping
- Reduces queries from N to 1 when loading site subscriber data
Impact:
- Prevents discovery worker crashes during SNMP timeouts
- Eliminates memory accumulation from leaked event handlers
- Prevents chart state loss on LiveView updates
- Prevents LiveView crashes from unexpected PubSub messages
- Improves database performance by eliminating N+1 queries in alert/device views
- Passes credo --strict with 0 issues

Replace the revoke functionality with delete to properly clean up agent references.
When an agent is deleted:
- All direct device assignments are removed
- Agent is removed from site defaults
- Agent is removed from organization defaults
- Devices automatically fall back to site/org agents or cloud polling
This ensures no orphaned references and provides better clarity about
what happens to device monitoring when an agent is removed.
