e2e: Logger Test Suite Enhancement

[BrodyHughes]

Fixes BX-1931

Adds comprehensive test coverage for the logger system with 39 tests across 3 test files:

What's tested:

• Core functionality: Log level hierarchy, transport system, metadata handling
• Error handling: RainbowError integration, error wrapping for non-RainbowError inputs
• Transports: Console transport formatting and Sentry breadcrumb/exception handling
• Debug contexts: Wildcard patterns (auth:*) and context-specific filtering
• Production patterns: Real-world error scenarios from RAPs and analytics
• Edge cases: Null values, circular references, large objects, transport failures
• Code quality: Validates no console.log/error in production code (except debug-flagged files)

Key improvements:

• Tests match actual usage patterns found in codebase
• Validates both console and Sentry transports work correctly
• Ensures proper error cause chains are preserved
• Confirms debug context filtering works as designed

All tests pass and run automatically with yarn test.
