feat: Enhance Microsoft Rewards Bot with recovery email normalization and improved logging

- Added `normalizeRecoveryEmail` utility function for consistent recovery email validation.
- Improved logging functionality in `Logger.ts` with enhanced edge case handling and null checks.
- Centralized browser cleanup logic in `BrowserFactory.ts` to eliminate duplication.
- Refactored error handling and message formatting in `Utils.ts` for better clarity and consistency.
- Updated various log messages for improved readability and consistency across the codebase.
- Implemented periodic cleanup of webhook buffers in `Logger.ts` using centralized constants.
