Add soft deletes via status column

- Add status ENUM('active','disabled','deleted') to 8 tables
- Change all physical DELETE to UPDATE status='deleted'
- All SELECT queries filter by status='active'
- toggleActive now alternates between active/disabled status
- Exceptions: monitoring_history, rate_limits, sessions keep physical purge
- audit_logs remains immutable
