View recent searches in the issue search bar

View recent searches in the issue search bar.
This is just using the browser's local storage. So it does not need to be persisted to the system. If you use a different browser, if you delete your history, if you use a different device, you won't see the history. Those are features that are not in scope here.

We'll add a "History" button to the left of the search bar that opens a dropdown.

The icon for the button is fa-history
The width of the dropdown is 320px
We show the 5 most recent searches
Search strings are shown in plain text, without the token style
Each recent search can take up to 2-3 lines (we'll decide what feels good when it's implemented)
If the search string is longer that those 2-3 lines, we cut it off with an ellipsis
The value side of the plain-text token uses font-weight:600
When clicking on a row, the search is performed. The previous search is replaced and the page reloads
Clear recent searches is a stretch goal
When there are no recent searches, a message shows up instead of the usual rows
