feat(backups): implement normalizeS3Path utility and integrate into backup processes

- Added normalizeS3Path function to standardize S3 path formatting by trimming whitespace and removing leading/trailing slashes.
- Updated backup-related modules (MySQL, MongoDB, PostgreSQL, MariaDB, and web server) to utilize normalizeS3Path for consistent S3 path handling.
- Introduced unit tests for normalizeS3Path to ensure correct functionality across various input scenarios.
