fix(destinations): handle empty and server-scoped destinations

Build the global destinations list from actual destination records so empty
servers do not render duplicate empty states. Allow creating Docker destinations
for a selected team server outside the global usable list, authorize swarm
creation correctly, and store discovered swarm network names from the selected
network. Add feature coverage for empty states, selected-server mounting, and
swarm destination creation.
