feat: default Vue Nodes (Nodes 2.0) to enabled for new cloud installs (#9009)

## Summary

Default Nodes 2.0 (`Comfy.VueNodes.Enabled`) to `true` for new cloud
installs (≥1.41.0).

## Changes

- **What**: Add `defaultsByInstallVersion: { '1.41.0': isCloud }` to the
`Comfy.VueNodes.Enabled` setting. Since `isCloud` is a compile-time
constant, cloud builds get `{ '1.41.0': true }` while local builds get
`{ '1.41.0': false }` (tree-shaken away).

## Review Focus

- Version threshold `1.41.0` — should this match a specific upcoming
release?
- Existing users (installed before 1.41.0) and non-cloud builds are
unaffected — they keep the `defaultValue: false` fallback.
