- Remove duplicate apply_client_rules function (second definition was overriding first)
- Improve zone-based firewall rule application:
- Proper MAC address normalization (uppercase)
- Clean rule names without colons (CG_BLOCK_AABBCCDD)
- Quarantine zone blocks WAN but allows DNS/DHCP
- Zone settings (internet_access, local_access) properly applied
- Firewall reload is now synchronous for immediate effect
- Improve remove_client_rules to find and delete all CG_ prefixed rules
- Add debug logging for troubleshooting
