Enhance database backup with compression support and backward compatibility

- Added configurable compression for database backups using gzip streaming
- Implemented auto-detection in restore function for compressed and uncompressed formats
- Added performance optimizations including --single-transaction and --extended-insert
- Created configuration file for gradual feature rollout with safe defaults
- Added helper functions for checking system capabilities and configuration
- Included comprehensive test suite to verify backward compatibility
- Maintained 100% backward compatibility with existing backup infrastructure
