Replace usage of search URL query params with different approach for reusable search URLs.

## Description

We are currently storing search query attributes like the time range and search query in the URL. This way users are able to bookmark a specific search or send the URL to a colleague without the need to create a saved search.

Since URLs have a max length of 2048 characters, this approach does not scale. Search queries will become more complex over time and we need to find a different solution to support the mentioned use cases.
