fix(nodes): bind form-encoded posts and skip node inbounds in central xray

The Node model only carried `json:` tags, so when the panel's axios
posted form-encoded bodies to /panel/api/nodes/add and /test, Gin's
form binder produced a zero-valued Node — empty Name, empty Address,
Port=0 — surfacing as "node name is required" and a probe URL of
"https://:0/...". Add `form:` tags so add/test bind correctly.

Also skip inbounds with NodeID set when building the central xray
config; otherwise the central panel tried to listen on ports owned by
node-managed inbounds and xray-core failed to start with a bind
collision.
