Feature: Last X minutes blocked queries list + whitelisting button

[fallmake]

I often find myself checking the querylog when some website/feature of a website doesn't work to see whether pi-hole blocked it and whitelisting if it's something I need rather than turning the pi-hole off and back on. Being able to see recent blocked entries in the extension with the ability to whitelist them as with Current Url would be very useful as it would be a quicker way to unblock the hosts causing the issue.

There's the API method /admin/api.php?getAllQueries&from=1664814000&until=16648154510&auth=<API_KEY> where from and until are unix timestamps. From=current time minus X seconds and until=current time would give us the recent queries. As per https://discourse.pi-hole.net/t/pi-hole-api/1863 column 5 should allow filtering to blocked queries (answer type=1 blocked by gravity.list) with column 3 containing the requested hostname. Example output with one resulting query:

{"data":[["1664814001","A","self.events.data.microsoft.com","devicename","1","2","4","5","N\/A","-1","N\/A#0",""]]}
