feat: add automatic cluster sync and IPAM discovery with configurable intervals, firewall log file parsing, and enhanced flow prioritization

Add RuntimeSettingsRead/RuntimeSettingsUpdate schemas with auto_node_sync_enabled/auto_node_sync_interval_minutes/auto_ipam_sync_enabled/auto_ipam_sync_interval_minutes/last_node_auto_sync_at/last_ipam_auto_sync_at fields, implement firewall_log_lines_from_files to parse /var/log/pve-firewall.log with max_lines limit and error collection, extend collect_firewall_log
