  Dashboard panel for `Integrations.HttpAbsent` (same package).

  Nested under the monitor's own namespace deliberately — the package's
  top-level module name never changes, and this module's name is
  guaranteed distinct from any separately-published standalone display
  package. `Display.BundledDefault` auto-hooks this whenever
  `Integrations.HttpAbsent` starts, the same as if they were still one
  module.
