- Remove Mox.set_mox_global() in DPW extra test; rely on $callers
instead so concurrent vendor SNMP tests stop intermittently failing
with VerificationError.
- Make ToweropsWeb.Plugs.GraphQLIntrospectionTest async: false. It
mutates Application.put_env(:towerops, :env, :prod), which polluted
every async vendor test that reads :env via
Towerops.Snmp.Client.phoenix_snmp_disabled/0.
- Bump test pool queue_target/queue_interval. AgentChannelTest spawns
many `:proc_lib` channel processes that hold sandbox connections;
the default 50ms queue caused intermittent
'could not checkout the connection' errors.
- Tag real-System.cmd("ping") tests as :network so they're excluded
by default. Saves ~20s on every full run.
- Make JobCleanupTask's internal 1s settle sleep configurable via
:job_cleanup_settle_ms; the test overrides it to 0.
Plus the pending CoverageLive.Form edit-save / EIRP recompute and
TraceLive deep-link tests from before the compact.
