fix: don't use registry when only checking for presence of missing nodes (#6965)

Changes the client-side validation of whether a graph has missing nodes
to use a simpler check (is the node name in the node defs from
`/object_info`), rather than using the Comfy Node Registry API
(api.comfy.org). The Registry API is still needed to get full
metadata/info about missing nodes, but that can be deferred until the
user actually needs that info.

This also fixes an issue where a node you coded yourself locally which
is neither a core node nor a node in the registry would be considered
"missing."
