Refactor LED toggle functionality in network.py to use DeviceSetLedStatus with fallback

[sirkirby]

This pull request refines the set_device_led method in custom_components/unifi_network_rules/udm/network.py to improve its robustness and flexibility. It introduces a two-step approach for toggling the LED status of a device, prioritizing a new method (DeviceSetLedStatus) with a fallback to the original minimal payload approach.

fixes #80

Enhancements to LED toggle functionality:

• Primary Approach: Added support for toggling LED status using DeviceSetLedStatus from aiounifi. This method provides a more structured and modern way to interact with the UniFi API.
• Fallback Approach: Retained the original minimal payload method as a fallback, ensuring compatibility with older UniFi Network versions. This approach uses the legacy API endpoint for device updates.

Logging improvements:

• Enhanced logging to provide detailed debug information for both the primary and fallback methods, including success and failure cases. This aids in troubleshooting and monitoring.

Error handling improvements:

• Improved exception handling for both approaches, ensuring that failures are logged clearly and the method gracefully handles errors without crashing.
