fix(config): use standalone bundled Node for runtime compatibility checks

Standalone OpenClaw ships its own Node.js and openclaw.cmd prefers that
binary over PATH. check_node() was inspecting the first system Node
(often an older nvm install), marking compatible=false and blocking
Gateway startup via ensure_node_runtime_compatible().

Prefer the bundled node next to the active standalone CLI when present,
and mirror the same logic in dev-api web mode.
