Fix: Conditional logging for 'Proceeding to mine blocks' message #5338

[Parikalp-Bhardwaj]

Summary

• This PR fixes an issue where the node logs Proceeding to mine blocks even when running as a follower node. The log message is now conditional on the node being a miner.

Changes

• Added a conditional check around the log message to ensure it only appears when the node is configured as a miner.

Related Issues

• Closes Node always logs "Proceeding to mine blocks" regardless of miner status #4944
