iframe regression tests for innerHTML guard + data-action fix (PR #3373).

Verifies that dynamically loaded UI elements whose inline onclick/onchange
handlers were converted to data-action + addEventListener still function
correctly when the admin UI is embedded inside an <iframe>.

The innerHTML guard (PR #3129) strips all on* attributes from HTML set via
innerHTML.  PR #3373 converts all affected paths to data-action + addEventListener
so that the guard no longer breaks interactivity.

These tests load the admin UI inside an iframe (using the ``iframe_host``
fixture from test_iframe_embedding_security.py) and assert that:

  1. Team selector dropdown items carry ``data-action="select-team"`` and
     have no ``onclick`` attribute after innerHTML load.
  2. Tool table action buttons carry ``data-action`` attributes and have no
     ``onclick`` attribute after innerHTML load.
  3. Metrics error/empty-state retry buttons carry
     ``data-action="retry-metrics"`` and have no ``onclick`` attribute.
  4. Global search result buttons carry ``data-action`` and have no
     ``onclick`` attribute after innerHTML load.
