Execute state transition for a block

This function processes all transactions in a block, updating both state and events databases. It handles transaction nonce validation, execution, and persistence. Only processes the block if it’s the next expected height.

Returns the resulting state and events roots along with their operation counts, plus a map of processed public keys to their next expected nonces.
