Replace database rule synchronization with native rule operations and file-based backup, import, and recovery. Update firewall management views, descriptions, whitelist handling, and translations.
Include terminal reconnect fixes and xpack build tags for Darwin build targets. Remove temporary regression test files before committing.
Port forwarding no longer shares the filter client. FilterClient keeps only
filter capabilities, and forwarding gets its own adapter, service and boot
replay:
- utils/firewall/forwarding holds the provider adapters. firewalld uses native
forward-port, ufw and iptables share the NAT implementation moved out of
client/iptables/forward.go.
- service/forwarding.go owns base info, search, operate, enable and replay.
The API keeps its routes and dispatches on name/type/operate.
- init/firewall replays forwarding through that service instead of loading NAT
rule files inline.
Also adds 1PANEL_FORWARD to the IptablesOp name enum: the frontend already
sends {"name":"1PANEL_FORWARD","operate":"init-forward"} and the validator
rejected it with 400 before reaching the service. Besides that, the only
observable difference is that a forward-tab search no longer triggers the
port/address record cleanup goroutine on the side.
