Add a button for expanding the time range when no tag values are returned

Today, when a user has data that is outside of the last hour, we show the following the the data explorer.

We should give the user the option to expand the time range to show all tags.

The feedback from users is that when they are loading historical data, their initial assumption when no tags are returned is that the data failed to load. providing an option to view all time might help alleviate that concern.

Start from the data explorer shown in the issue and reproduce the empty-tag state with a last-hour time range. Trace the frontend entry point that renders this state; done means users can expand the range and see historical tag values instead of assuming data failed to load.
