Add Synology monthly drive health report parser

Add parser for Synology monthly drive health reports with support for both
Dutch and English notifications. Reports are classified as informational
and excluded from schedule learning and reporting logic.

Features:
- Recognizes Dutch ("Maandelijks schijfintegriteitsrapport", "Gezond") and
  English ("Monthly Drive Health Report", "Healthy") variants
- Extracts hostname from subject or body ("Van/From NAS-HOSTNAME")
- Automatic status detection: Healthy/Gezond/No problem detected → Success,
  otherwise → Warning
- Backup type: "Health Report", Job name: "Monthly Drive Health"
- Added registry entry (order 237) for /parsers page visibility

 ## [2026-02-09]
 
 ### Added
+- Added parser for Synology monthly drive health reports (backup software: Synology, backup type: Health Report, job name: Monthly Drive Health, informational only, no schedule learning) with support for both Dutch and English notifications ("schijfintegriteitsrapport"/"Drive Health Report") and automatic status detection (Healthy/Gezond → Success, problems → Warning)
 - Added "Cleanup orphaned jobs" maintenance option in Settings → Maintenance to delete jobs without valid customer links and their associated emails/runs permanently from database (useful when customers are removed)
 - Added "Preview orphaned jobs" button to show detailed list of jobs to be deleted with run/email counts before confirming deletion (verification step for safety)
 - 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)
