Pull request overview

This PR enhances the local push notification reliability by implementing automatic reconnection logic with exponential backoff and extensive diagnostic logging. The changes aim to handle network disruptions more gracefully by detecting when local push becomes unavailable and automatically attempting to re-establish the connection.

Key changes:

• Adds automatic reconnection mechanism with backoff delays (5s, 10s, 30s) when local push connections fail
• Introduces comprehensive verbose logging throughout the local push infrastructure for better debugging
• Refactors manager configuration code into smaller, well-documented helper methods
