Add semantic mappings for rules without NIST references

Map 48 previously unmapped rules (without NIST references in metadata)
to appropriate NIST 800-53 controls using semantic analysis of rule
descriptions and rationales. These rules were identified through keyword
matching and manual review.

Changes across rhel8, rhel9, and rhel10:

CP (Contingency Planning) family:
- cp-9 (System Backup): +3 backup-related rules
  - configure_user_data_backups
  - file_groupowner_backup_etc_shadow
  - httpd_remove_backups

SC (System and Communications Protection) family:
- sc-7 (Boundary Protection): +25 firewall rules
  - firewalld, iptables, nftables, ufw configuration rules
  - Firewall zone, policy, and port management rules
  - Total rules in sc-7: 36 (11 existing + 25 new)

AU (Audit and Accountability) family:
- au-3 (Audit Record Content): +1 login event audit rule
- au-3.1 (Additional Audit Information): +5 network config audit rules
- au-5 (Audit Failure Response): +2 audit system resilience rules
- au-9 (Protection of Audit Information): +3 audit protection rules
- au-12 (Audit Record Generation): +9 additional syscall audit rules

These mappings address rules that lacked explicit NIST references but
provide technical controls that satisfy the control requirements. Total
new mappings: 144 (48 unique rules × 3 products).
