[Bug]: Avoid skipping the rest of the block if we err when processing an event in new block handler

Chore - Avoid skipping the rest of the block if we err when processing an event in new block handler

1. Description

In the new block handler, we currently return at the first error when processing the events:

sbtc/signer/src/api/new_block.rs

Lines 161 to 164 in e4c6b5f

	Err(error) => {
	tracing::error!(%error, "got an error when transforming the event ClarityValue");
	return StatusCode::OK;
	}

Doing so, we will skip all the successive events in the same block. Instead, we should just continue (or return an err and stall the process?).
