fix(#662): cron fleet audit — crontab parsing, tests, CI validation

- Added VPS crontab backup parsing to cron-audit-662.py
- New audit_fleet() combines hermes cron + VPS crontabs
- load_crontab_backups() reads cron/vps/*-crontab-backup.txt
- 20+ tests: crontab parsing, job categorization, fleet audit,
  timestamp parsing, backup loading
- ci-cron-validate.py: CI gate that fails on systemic failures
- Fresh audit report generated in cron/audit-report.json

Closes #662
