Extend Synology Active Backup for Business parser for skipped tasks

Extended the parser to recognize backup tasks that were skipped/ignored
because a previous backup was still running. These are treated as Warning
status for monitoring purposes.

Changes:
- Extended _ABB_COMPLETED_RE regex to match "genegeerd" (NL) and "skipped"/"ignored" (EN)
- Added "van deze taak" pattern for Dutch phrasing variations
- Added status detection for skipped tasks (Warning with "Skipped" message)
- All existing patterns remain functional (backward compatible)
- Updated changelog

 - Added "Generate test emails" feature in Settings → Maintenance with three separate buttons to create fixed test email sets (success/warning/error) in inbox for testing parsers and maintenance operations (each set contains exactly 3 Veeam Backup Job emails with the same job name "Test-Backup-Job" and different dates/objects/statuses for reproducible testing and proper status flow testing)
 - Added parser registry entry for Synology DSM automatic update cancelled notifications (backup software: Synology, backup type: Updates, informational only, no schedule learning)
 - Extended Synology DSM update parser with additional detection patterns ("Automatische DSM-update", "DSM-update op", "Packages on", "out-of-date", "Package Center", "new DSM update", "Auto Update has detected", "Update & Restore") and hostname extraction regex to recognize DSM update cancelled, out-of-date packages, and new update available notifications under same Updates job type while maintaining backward compatibility with existing patterns
+- Extended Synology Active Backup for Business parser to recognize skipped/ignored backup tasks ("genegeerd", "skipped", "ignored") as Warning status when backup was skipped due to previous backup still running
 
 ### Changed
 - Removed customer name from Autotask ticket title to keep titles concise (format changed from "[Backupchecks] Customer - Job Name - Status" to "[Backupchecks] Job Name - Status")
