test: lift coverage 79.78% → 80.92%+ with broad new tests
Adds 100+ new tests across:
- Snmp.Discovery sync_*: mempools/transceivers/printer_supplies/
entity_physical/save_neighbors/save_arp_entries
- Topology: compute_wireless_stats, compute_rf_link_stats,
get_topology_for_weathermap, LLDP discovery/list/upsert,
remove_stale + find_device_by_name fallthroughs
- Trace: account/inventory/access_point assemble_trace + trace_from_device
inventory→account linking
- DiscoveryWorker: assigned-agent fallback, agent offline mid-discovery,
device deleted during discovery, perform/1 rescue (34% → 64%)
- Snmp.Profiles.Base: discover_state_sensors/vlans/ipv6_addresses/
memory_pools/processors + identify_device for many vendors
- ChartBuilders: load_*_chart_data nil/empty + DB-backed sensor charts
- OrgSettingsLive events: apply_snmp/apply_agent/toggle_default/
toggle_enabled
- DeviceLive.Form events: edit access errors, validate branches,
test_snmp w/o agent + with v2c/v3 credentials, query param prefill
- DeviceLive.Index: reorder, search, filter_status, force rediscover
- CheckLive.FormComponent: full mount/change_type/validate/save flow
for http/tcp/dns/ssl + edit/close
