Make is easy to search for specific companies (or municipalities) in the ComparisionTable

[Greenheart]

Investigate if there's an easy way to implement a basic search functionality.

Maybe add a search icon above the ComparisionTable that can be expanded into a search field.

When searching for something, ideally show suggestions based on the most relevant items from the list

When selecting an item from the search results, scroll to it in the table. Maybe using Element.scrollIntoView(). We could potentially get the DOM reference from the rendered table rows of @tanstack/table.

Marking as not ready for now, since #551 will make it easier to navigate the table. Then we might reconsider this as part of the redesign.
