perf(inbounds): share nodes list with form modal instead of refetching

InboundsPage and InboundFormModal both called useNodes() — each
instance maintains its own state and fires its own /panel/api/nodes/list
fetch on mount. Since the modal is always rendered (open or not), every
page load hit the endpoint twice.

Threaded nodes from the page through an availableNodes prop on the form
modal so they share one fetch.
