feat(persistence): fix QuotaExceededError and cross-workspace draft leakage (#8520)

## Summary

Completes the workflow persistence overhaul by integrating the new draft
system into the app and migrating existing data. Fixes two critical
bugs:

1. **QuotaExceededError** - localStorage fills up with workflow drafts,
breaking auto-save
2. **Cross-workspace data leakage** - Drafts from one ComfyUI instance
appear in another

## Changes

- **What**: 
- `useWorkflowPersistenceV2.ts` - Main composable that hooks into graph
changes with 512ms debounce
- `migrateV1toV2.ts` - One-time migration of existing drafts to the new
scoped format
  - Updated E2E tests for new storage key patterns
- **Why**: Users lose work when storage quota is exceeded, and see
confusing workflows from other instances

## How It Works

- **Workspace scoping**: Each ComfyUI instance (identified by server
URL) has isolated draft storage
- **LRU eviction**: When storage is full, oldest drafts are
automatically removed (keeps 32 most recent)
- **Tab isolation**: Each browser tab tracks its own active/open
workflows via sessionStorage
- **Debounced saves**: Graph changes are batched with 512ms delay to
reduce storage writes

## Migration

Existing V1 drafts are automatically migrated on first load. The
migration:
1. Reads drafts from old `Comfy.Workflow.*` keys
2. Converts to new workspace-scoped format
3. Cleans up old keys after successful migration
