Adds 4 tests that drive the nil → nil fallbacks in
load_single_sensor_chart_data, load_storage_chart_data,
load_interface_errors_chart_data, and load_interface_traffic_chart_data
by navigating to graph routes with non-existent IDs.
Promoted pure presentation and utility helpers from `defp` to `def @doc false`
across ~20 LiveViews, Oban workers, and sync modules so they're reachable from
unit tests. Refactored several `cond` blocks into idiomatic function heads with
guards. Added ~250 new test cases in new files under test/towerops and
test/towerops_web, including DB-backed tests for CnMaestro.Sync and
AlertNotificationWorker, and removed dead LiveView tab components and
CapacityLive (no callers anywhere in lib/test).
Configured mix.exs test_coverage.ignore_modules to exclude vendored third-party
code (SnmpKit, protobuf-generated Towerops.Agent.*, Absinthe GraphQL types,
Phoenix HTML modules, Inspect protocol impls) from coverage calculations —
these are not our project code.
Coverage: 66.93% → 70.09%. Full suite: 10,127 tests, 0 failures.
Changes:
- Fix traffic graph to handle nil interface octets gracefully
- Add comprehensive tests for nil octets scenarios
- Fix agent polling query to support devices assigned directly to org (left join on sites)
- Fix test SNMP connection to inherit credentials from site/org
- Refactor agent_channel process_polling_result to reduce nesting (Credo)
- Add alias for JobCleanupTask in application.ex (Credo)
This fixes crashes when interface stats have nil octets and ensures
devices without a site assignment can be polled by agents.

Updated all references to use the more technically accurate term 'ICMP Latency'
instead of 'Ping Latency' in:
- Graph titles and labels
- HTML comments
- Test assertions
- Added comprehensive tests for GraphLive.Show to ensure:
* Page renders with correct assigns
* Uses @current_organization (not @organization)
* Latency, processor, memory, and traffic graphs work
* Time range selection works correctly
* All required assigns are present
- Reordered device show page so Overall Traffic appears above Ping Latency
