feat: client-side distribution filtering for blueprint subgraphs (#8686)

Adds client-side filtering of blueprint subgraphs by distribution.

**Changes:**
- Added `includeOnDistributions` typed field to `GlobalSubgraphData` in
`api.ts`
- Distribution detection: `isCloud → 'cloud'`, `isDesktop → 'desktop'`,
else `'localhost'`
- Filters subgraphs before loading — excluded blueprints are never
fetched

**Depends on:** Comfy-Org/workflow_templates schema update (merge first)
