Added new maintenance option in Settings → Maintenance to delete
jobs that are no longer linked to an existing customer (customer_id
is NULL or customer doesn't exist).
Features:
- Finds all jobs without valid customer link
- Deletes jobs, runs, and related emails permanently
- Cleans up auxiliary tables (ticket_job_runs, remark_job_runs,
scopes, overrides)
- Provides feedback on deleted items count
- Logs action to audit log
Use case: When customers are removed, their jobs and emails should
be completely removed from the database.
