Invalid Nonce Validation

Currently, nonce validation in Sourcify Monitoring appears to restrict values ​​that are within the allowed uint64 range. The value 12894333551438793358 (which is within the uint64 limit) is incorrectly rejected. This prevents contracts in a given block from being analyzed.

• Technicall details:
  The nonce: 0xb2f1e00c44e90a8e -> 0<12894333551438793358 < 18446744073709551615 [Uint64]

• The impact of this issue is significant, as the monitoring process remains blocked until the nonce validation is correctly performed. This disrupts the normal execution flow and may affect critical systems that rely on a continuous sequence of transactions.

Start with the monitor service and its block-fetch path, using the Docker reproduction with monitorChains.json and config.json for VeChain Mainnet. Reproduce the failure at block 21380962 and trace how the logged nonce is parsed. Done means the block fetch succeeds and contracts in that block can be analyzed without rejecting the valid uint64 nonce.
