3c787e005f Fix bug in the scanner regarding forwarded output amounts
We'd report the amount originally received, minus 2x the cost to aggregate,
regardless the amount successfully forwarded. We should've reduced to the
amount successfully forwarded, if it was smaller, in case the cost to
forward exceeded the aggregation cost.

fadc88d2ad Add scheduler-primitives
The main benefit is whatever scheduler is in use, we now have a single API to
receive TXs to sign (which is of value to the TX signer crate we'll inevitably
build).

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).

76cbe6cf1e Have acknowledge_block take in the results of the InInstructions executed
If any failed, the scanner now creates a Burn for the return.

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.

75251f04b4 Use a channel for the InInstructions
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.
