feat: add inbound share address strategy (#5162)

* feat: add inbound share address strategy

Allow node-managed inbounds to choose whether exported share links use the node address, routable listen address, or a custom endpoint. Preserve locally configured share address fields during remote node traffic sync.

Refs #5161

Refs #4891

* fix: preserve inbound share address settings

Forward share address fields to remote nodes, keep existing values when older update payloads omit them, align localhost handling between frontend and subscriptions, and preserve share address settings when cloning inbounds.

* fix: keep share address strategy out of subscriptions

Limit the new share address strategy to direct exported share links and QR codes. Restore subscription address resolution to the existing panel-owned behavior and update the UI help text accordingly.

* fix: address share address review feedback

* fix: validate custom share address

* fix
