This PR fixes an issue where the AI search results were not being reset when you append your search to an existing query param (typically when you've come from quick search). This is because `handleSearch()` doesn't get called in this situation. So here we explicitly check for query params, trigger a reset and search for those occasions.
Previously we had some hardcoded markup with scss making a loading indicator wave. This code was being duplicated and used in both semantic search and summarization. We want to add the indicator wave to the AI helper diff modal as well and have the text flashing instead of the loading spinner. To ensure we do not repeat ourselves, in this PR we turn the summary indicator wave into a reusable template only component called: `AiIndicatorWave`. We then apply the usage of that component to semantic search, summarization, and the composer helper modal.
