cleanup: Remove all emoji logs

Removed all logging statements containing emoji characters:
- 🔴 red circle (debug logs)
- 🔥 fire (critical debug markers)
- 🟢 green circle (info logs)
- Other emoji symbols

Also removed unused replicaID variable that was only used for debug logging.

Code is now clean with production-quality logging.
