13b74195f7 Don't have acknowledge_batch immediately run 
`acknowledge_batch` can only be run if we know what the Batch should be. If we
don't know what the Batch should be, we have to block until we do.
Specifically, we need the block number associated with the Batch.

Instead of blocking over the Scanner API, the Scanner API now solely queues
actions. A new task intakes those actions once we can. This ensures we can
intake the entire Substrate chain, even if our daemon for the external network
is stalled at its genesis block.

All of this for the block number alone seems ridiculous. To go from the block
hash in the Batch to the block number without this task, we'd at least need the
index task to be up to date (still requiring blocking or an API returning
ephemeral errors).

41a74cb513 Check a queued key has never been queued before 
Re-queueing should only happen with a malicious supermajority and breaks
indexing by the key.

e26da1ec34 Have the Eventuality task drop outputs which aren't ours and aren't worth it to aggregate 
We could drop these entirely, yet there's some degree of utility to be able to
add coins to Serai in this manner.

It's still unclear how we'll handle refunding failed InInstructions at this
time. Presumably, extending the InInstruction channel with the associated
output ID?

useful and I don't want to make a dedicated crate yet.

bc0cc5a754 Decide flow between scan/eventuality/report 
Scan now only handles External outputs, with an associated essay going over
why. Scan directly creates the InInstruction (prior planned to be done in
Report), and Eventuality is declared to end up yielding the outputs.

That will require making the Eventuality flow two-stage. One stage to evaluate
existing Eventualities and yield outputs, and one stage to incorporate new
Eventualities before advancing the scan window.
