[Test] LogManager type casting errors in configuration handling

Which jobs/test(s) are failing

test/log_manager_test.dart:LogManager creates default channel
test/log_manager_test.dart:LogManager creates specific channel
test/log_manager_test.dart:LogManager creates stack channel

Reason for failure/description

Type casting errors when handling configuration in LogManager. Two specific error patterns:

1. type 'String' is not a subtype of type 'Map<String dynamic>'
2. type 'Null' is not a subtype of type 'Map<String dynamic>'

The errors occur in MockApplication.make() and propagate through the LogManager's configuration methods. This suggests an issue with how configuration data is being handled in the test environment.

Is this a regression?

No

Media proof

type 'String' is not a subtype of type 'Map<String dynamic>' in type cast
  test/log_manager_test.dart 43:37                  MockApplication.make
  package:platform_log/src/log_manager.dart 48:38   LogManager.getDefaultDriver

• Location: packages/log/test/log_manager_test.dart
• The issue appears to be in the mock application setup for testing
• Affects all LogManager configuration-related functionality
