Show some short-lived popup when a new solicitation is up

[db0]

Just an idea to help people notice there's instances asking for a guarantee.

Now and then poll the solicitations in the background. When a new one is found, put a short-lived popup that asks the user to take a look at new solicitaitons

The popup should not appear if the user has maxed out their guarantees (so, dependent on me adding Fediseer/fediseer#31 first. The popup should not appear if you have the instance hesitated/censured.

Perhaps to filter it a bit more, have the popup only appear if the solicitating instance is not censured/hesitated by any of your instances's endorsements either.
