feat: recheck pin status on GET /pins/:req-id (#2214)

When using kubo to `ipfs remote pin add` we get a GET request every
second checking for an update to the pin status.

Here we use that as a trigger to ask pickup for a status update. This
will be handled by a lambda invocation and a single item db read, and
will be pretty low impact.

In return we will be able to inform the user as soon as their pin is
complete rather than having to wait up to an hour for an async pin
update job to complete.

fixes #2213
