The configuration option `StartAsNonProducingNode` was ignored, one could only use the switch `--non-producing-node` to set it. In this patch we fix this, and now it can be set either with the switch or if it's not given, it can be set in the configuration file.
The default configuration value of peer sharing option depends now on `pncStartAsNonProducingNode` option and `ncProtocolFiles`. If a node runs as a relay, peer sharing is on by default, if it is running as a block producer, peer sharing is off by default. The default value can be overridden.
The old option is kept, but deprecated.

Point the ouroboros-consensus SRP at 80c800f (50c9711 + Forker fix that rejects an invalid CertRB Leios cert as InvalidBlock rather than crashing the node) and handle the new ExtValidationErrorLeios constructor in the ChainDB LogFormatting instance so tracing the rejected block does not hit a pattern-match failure.

This is optional so we have always a way to "turn off" voting (at the risk of forgetting the new option)

* Moved to a new module * Provide re-usable API This is a preparation work for re-using the CDF calculations for Leios.

…are gone Two bugs stopped --outputs-per-tx > 1 from running for more than a few seconds, both showing up as "insufficient funds - total inputs (364400 lovelace) do not cover fee (1000000)". takeInputs picks by TxIn order, i.e. effectively at random, so it could select `target` dust entries and split their sum `target` ways — producing finer dust, and repeating. 364,400 lovelace sits exactly in the divide-by-5 sequence down from the original 30M ADA, with the value itself untouched (29,999,924,000,000 across 305 UTxOs) simply because it was never selected. takeLargest instead takes the `target` largest funds, extending with the next largest until they cover fee + target * outputFloor, so an output is never created too small to spend again and stranded dust gets consolidated rather than sharpened. That also subsumes the fan-out case, so takeFattest goes. Separately, keeping the inputs on a reject is right for a transient failure but wrong when the ledger says they are gone: takeInputs is deterministic, so the retry rebuilt the same tx and earned the same rejection until max-consecutive-errors. Worse at startup with a single UTxO and a fan-out target, where that one tx is the only one buildable. Measured on dozen-devnet: --outputs-per-tx 5 gives 648 B transactions, 5 in / 5 out, no failures.

Description
This PR hosts changes to cardano-node related to Leios. I'm opening a PR for easier management and transparency to make changes visible at a glance.
More importantly, this branch will be tagged and sourced for Leios demos.
IT IS NOT INTENDED TO BE REVIEWED OR MERGED!
