TxBodyContent refactoring related fixes

chore(onchain): remove 17 aiken warnings

This was preventing the offers to be released.

This should not be needed as soon as we have implemented eb
announcements. Then, the point would already be there, or the fetching
logic should have not decided to download an unknown EB.

Only check completeness based on just inserted txHashes. Unfortunately
we don't have JSON1 functions available in the presently available
sqlite build, but this would be an even more efficient way to do this.

The LeiosDb now stores the principal information which txs we already
have, across all ebs (n:m). The storing and later copying from the
intermediate in-memory state is not needed anymore.

The previous `die` call was not showing up properly in the observability
stack. This now gives at least the chance to be visible as a big fat
error :x:

`die` just raises an exception and is not easily picked up by the
observability stack

Moves the notification mechanism into the `LeiosDbHandle` to allow
convenient access from the block forging loop in the `NodeKernel` and
simplify the issuance of notifications by keeping it local to the leios
db (to become the `LeiosEBStore`?).

With these changes, the forged endorser block bodies are submitted
through the network :tada:

What do you think of the notification mechanism via `TChan`?
