Add date/time picker to logs page

The logs api has the ability to filter via from_timestamp and to_timestamp. You can already pass these query string parameters into the logs ui endpoint to filter the results, but we should also add a date/time picker to the ui to make the user experience a bit nicer.

Start by locating the logs UI endpoint and the existing handling of the from_timestamp and to_timestamp query parameters. Inspect how the logs page builds its filters, then determine the appropriate UI entry point for a date/time picker. Done means users can select a range in the logs page and the results are filtered through those existing parameters.
