Zoltán Papp fffb9dd219 [client/ui-wails] Add Forwarding service for the exposed-services list
Surfaces the daemon's existing ForwardingRules RPC as a Wails service so
the React frontend can render the reverse-proxy / exposed-services list
in the planned dashboard.

Forwarding.List() returns one ForwardingRule per active rule with
protocol, destination port (single or range), translated address /
hostname, and translated port. The PortInfo oneof from the proto is
flattened to a `{port?: number, range?: {start, end}}` shape so TS
consumers don't have to peek at proto-internal type discriminators.

Regenerate frontend/bindings (forwarding.ts, models.ts, index.ts) so
the React side picks up the new service. peers.ts churn is a doc
comment refresh only — no API change.
