network_events: idx_event_lookup (event_type, target_name, target_detail, resolved_at)
- Covers the upsert_event SELECT which runs every cycle per monitored entity
- Replaces three separate single-column index scans with one covering lookup
suppression_rules: idx_sup_lookup (active, target_type, target_name, target_detail)
- Covers is_suppressed() queries (now redundant for runtime due to in-memory
check_suppressed, but ensures fast get_active_suppressions() loading per cycle)
Both indexes created on live DB (MariaDB LXC 149).
