[feat] Implement media asset workflow actions with shared utilities (#6696)

## Summary

Implements 4 missing media asset workflow features and creates shared
utilities to eliminate code duplication.

## Implemented Features

### 1. Copy Job ID ✅
- Properly extracts promptId using `getOutputAssetMetadata`
- Uses `useCopyToClipboard` composable

### 2. Add to Current Workflow ✅
- Adds LoadImage/LoadVideo/LoadAudio nodes to canvas
- Supports all media file types (JPEG, PNG, MP4, etc.)
- Auto-detects appropriate node type using `detectNodeTypeFromFilename`
utility

### 3. Open Workflow in New Tab ✅
- Extracts workflow from asset metadata or embedded PNG
- Opens workflow in new tab

### 4. Export Workflow ✅
- Exports workflow as JSON file
- Supports optional filename prompt

## Code Refactoring

### Created Shared Utilities:
1. **`assetTypeUtil.ts`** - `getAssetType()` function eliminates 6
instances of `asset.tags?.[0] || 'output'`
2. **`assetUrlUtil.ts`** - `getAssetUrl()` function consolidates 3 URL
construction patterns
3. **`workflowActionsService.ts`** - Shared service for workflow
export/open operations
4. **`workflowExtractionUtil.ts`** - Extract workflows from jobs/assets
5. **`loaderNodeUtil.ts`** - Detect loader node types from filenames

### Improvements to Existing Code:
- Refactored to use `formatUtil.getMediaTypeFromFilename()`
- Extracted `deleteAssetApi()` helper to reduce deletion logic
duplication (~40 lines)
- Moved `isResultItemType` type guard to shared `typeGuardUtil.ts`
- Added 9 i18n strings for proper localization
- Added `@comfyorg/shared-frontend-utils` dependency

## Input Assets Support

Improved input assets to support workflow features where applicable:
- ✅ All media files (JPEG/PNG/MP4, etc.) → "Add to current workflow"
enabled
- ✅ PNG/WEBP/FLAC with embedded metadata → "Open/Export workflow"
enabled

## Impact

- **~150+ lines** of duplicate code eliminated
- **5 new utility files** created to improve code reusability
- **11 files** changed, **483 insertions**, **234 deletions**

## Testing

✅ TypeScript typecheck passed  
✅ ESLint passed  
✅ Knip passed
