* Replace pigz with zstd for backup compression
This change replaces pigz (parallel gzip) with zstd (Zstandard) as the
compression algorithm for mailcow backups while maintaining full backward
compatibility with existing .tar.gz backups.
Benefits:
- Better compression ratios (12-37% improvement in tests)
- Improved compression speed with modern algorithm
- Maintains rsyncable functionality for incremental backups
- Full backward compatibility for restoring old .tar.gz backups
- Wide industry adoption and active development
Changes:
- Backup compression: pigz --rsyncable -p → zstd --rsyncable -T
- Backup decompression: pigz -d -p → zstd -d -T
- File extensions: .tar.gz → .tar.zst
- Added get_archive_info() function for intelligent format detection
- Updated backup Dockerfile to install zstd alongside pigz
- Restore function now auto-detects and handles both formats
- Updated FILE_SELECTION regex to recognize both .tar.zst and .tar.gz
- Updated comments to reflect new file extension
Backward Compatibility:
- Restore automatically detects .tar.zst (preferred) or .tar.gz (legacy)
- Existing .tar.gz backups can still be restored without issues
- pigz remains installed in backup image for legacy support
- Graceful fallback if backup file format not found
Testing:
- Added comprehensive test suite (test_backup_and_restore.sh)
- 12 automated tests covering all scenarios:
* Backup creation (both formats)
* Restore (both formats)
* Format detection and priority
* Error handling (missing files, empty dirs)
* Content integrity verification
* Multi-threading configuration
* Large file compression (8.59 MB realistic data)
Test Results:
✓ zstd compression working
✓ pigz compression working (legacy)
✓ zstd decompression working
✓ pigz decompression working (backward compatible)
✓ Archive detection working
✓ Content integrity verified
✓ Format priority correct (.tar.zst preferred)
✓ Error handling for missing files
✓ Error handling for empty directories
✓ Multi-threading configuration verified
✓ Large file compression: 37.05% improvement
✓ Small file compression: 12.18% improvement
* move testing script into development folder

* watchdog: use dig instead of check_dns
check_dns is slower and uses more system resources,
dig wrapped in a script is a more performant approach and uses
fewer system resources
* added debug mode + compose image bump

Previously imapsync only attached the timeout1 / timeout2 arguments if the argument was negative (which is not even possible). Now the argument is added for every positive number.
Fixes#6590
* [DB][Web] optimize qhandler by keeping SHA2(id+qid) in new column quarantine.qhash, for feature #6555, might also help with #6361
* rspamd: only add qhash to new entries while passing rspamd not all existing
* compose: bump dovecot image + push to registry
