feat: allow selecting inbounds synchronized from nodes (#5178)

* feat: select node inbounds for synchronization

Allow node owners to import either all remote inbounds or an explicit tag-based selection. Add remote inbound discovery, persistence, snapshot filtering, API documentation, tests, and localized UI labels.

* fix

* fix: scope node reconcile and orphan sweep to selected inbound tags

In 'selected' sync mode unselected inbounds never enter the panel DB, so
ReconcileNode treated them as undesired and deleted them from the node the
first time it went config-dirty. Reconcile now only sweeps remote tags that
are part of the selection; everything else on the node is unmanaged.

Panel-created or renamed inbounds on a selected-mode node also vanished:
their tag was outside the selection, so the next traffic pull filtered them
out of the snapshot and the orphan sweep silently dropped the central row.
AddInbound/UpdateInbound now allow the tag on the node before committing.
