Bug: Undefined access from empty input addresses array
Potential undefined access when vin.addresses is an empty array. According to the BlockbookTransaction type definition, addresses can be an empty array (default value is []). For SparkSpend inputs in FIRO (the purpose of this PR), the addresses array may be empty. Accessing vin.addresses[0] on line 1371 will return undefined, which is then passed to validScriptPubkeyFromAddress. While the try-catch will handle the error, the error message on line 1376 will log undefined as the address, making debugging difficult. The code should check if vin.addresses[0] exists before attempting to use it.
This handles only the receiving inputs side of a transaction. It does not fully support tracking the wallet's own SparkSpend inputs which it cannot even make currently because FIRO is transparent-only for now.

Fixes FIRO SparkSpend transaction processing by accepting inputs without txid (using zero txid) and making vin scriptPubkey derivation resilient; also standardizes coinbase outputIndex.
src/common/utxobased/engine/UtxoEngineProcessor.ts):vin.txid(fallback to000...000) to support FIRO SparkSpend/private inputs; remove null-txid error.scriptPubkeyderivation with try/catch and warning logs; default to"unknown"on failure.0xfffffffffor coinbaseoutputIndex.Written by Cursor Bugbot for commit 8e348af.
