Add test_combined_retention_policies to verify all 5 retention policies (keep_all, keep_daily, keep_weekly, keep_monthly, keep_yearly) work correctly together. Test validates precedence rules where later retention tiers can override earlier ones (e.g., monthly overrides weekly, yearly overrides monthly) and documents threshold inclusive behavior. Test uses 36 backups spanning 2017-2021 with expected 21 backups kept based on policy interaction.
