<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p><code>\Drupal\ai\AiVdbProviderInterface::getConfig()</code> is only used in <code>\Drupal\ai\Base\AiVdbProviderClientBase::validateSettingsForm()</code> to check that the Vector DB is configured. We already have a method for that.</p>
<p>Some VDB providers don't store config, and requiring ImmutableConfig requires a lot of workarounds.</p>
