Implement network resilience features for improved upload stability during network changes

- Enable network events by default in configuration
- Integrate network resilience manager into upload handling
- Add support for automatic upload pause/resume during WLAN to 5G transitions
- Enhance documentation with network resilience settings and testing procedures
- Create a test script for validating network resilience functionality
