feat(logging): start collecting logs at appMount

[andrei-gavrilescu]

Logs that would happen before SET_CONFIG logging middleware wouldn't be captured by the logger (which sends the data to rtcstats), logs such as
2025-08-11T08:28:49.586Z [features/base/config] Extending config with: {"videoQuality":{"preferredCodec":"VP9"}}
This moves the init of the logger to app mount, allowing it to capture more logs, even before the config is completely merged.

Pull Request Overview

This PR moves the initialization of the logging system to the app mount phase to capture logs that occur before the configuration is fully merged. Previously, logs generated before the SET_CONFIG action were not captured by the logger.

• Adds early logging initialization during app mount with minimal configuration
• Refactors the logging initialization into smaller, focused functions
• Updates log collector configuration to happen after config is available

The condition logic has been inverted. The original code checked if (isTestingEnabled && typeof APP === 'object') but now it returns early when either condition is false, which means the debug logging setup will never execute.

Directly assigning to logCollector.maxEntryLength may not properly update the log collector's configuration. The original code passed this value during construction. Consider using a proper configuration method if available.

Suggested change

	logCollector.maxEntryLength = rtcstatsLogFlushSizeBytes;
	if (typeof logCollector.setMaxEntryLength === 'function') {
	logCollector.setMaxEntryLength(rtcstatsLogFlushSizeBytes);
	} else {
	// Fallback to direct assignment if setter is not available.
	logCollector.maxEntryLength = rtcstatsLogFlushSizeBytes;
	}
