ServiceRadar v1.4.40

Compacts the operations dashboard so more of it fits without scrolling,
tags SNMP walk rows with ifIndex, and makes wait-migrations prove the
schema is current.

Whats New

1.4.40

• Dashboard: KPI, map, and events load independently so the map no
  longer blocks Total Assets. NetFlow map sits beside Events Over
  Time, with observability metrics under that chart. (PR #3819)
• Dashboard: shrink the map and events cards so the trio row and
  Alerts Feed fit on a typical desktop viewport. Grow the metrics
  sparklines under Events, and stop Threat Intel headers from wrapping
  into each other. (PR #3821)
• SNMP: walk rows on IF-MIB carry if_index / ifindex:N instead of
  a null index, so walked interface metrics show on the device
  Interfaces tab. (PR #3819)
• Helm: wait-migrations checks that the latest migration is applied,
  not merely that schema_migrations exists. A skipped hook can no
  longer start web-ng against a months-behind schema. (PR #3820)
• CI: native add-on version-bump gate runs on pull requests. The
  signing runner uses --config=remote so release publish can
  authenticate. (PRs #3818, #3816)
• Tests: Dgraph cluster setup for integration tests. (PR #3817)
• Tests: dashboard layout CSS is staged for Bazel so phoenix_live
  unit tests find app.css on RBE.
