feat: Add sort functionality to Media Asset Panel (#6695)

## Overview
Adds sort functionality to the Media Asset Panel. Users can sort assets
by creation time in Cloud environments.

## Key Changes

### 1. Sort Functionality (Cloud Only)
- "Newest first" (most recent)
- "Oldest first" (oldest)
- Sorting based on `create_time` field (output assets)
- Sorting based on `created_at` field (input assets)
- Sort button is only displayed in Cloud environments

### 2. create_time Field Integration
**Related PR**: #6092

Implemented sort functionality using the `create_time` field introduced
in PR #6092. Applied the code from that PR directly to the following
files:

- `src/schemas/apiSchema.ts`: Added `create_time` field to `zExtraData`
- `src/stores/queueStore.ts`: Added `createTime` getter to
`TaskItemImpl`
- `src/platform/remote/comfyui/history/types/historyV2Types.ts`: Added
`create_time` to History V2 API response types
- `src/platform/remote/comfyui/history/adapters/v2ToV1Adapter.ts`: Pass
through `create_time` in V2→V1 adapter
- `src/platform/assets/composables/media/assetMappers.ts`: Include
`create_time` in asset metadata

### 3. Component Structure Improvements
Created new components following existing component styles for
consistency:

- **`MediaAssetSearchBar.vue`**: Component combining existing SearchBox
with sort button
- **`AssetSortButton.vue`**: Same structure as `MoreButton.vue`
(IconButton + Popover)
- **`MediaAssetSortMenu.vue`**: Same style as `MediaAssetMoreMenu.vue`
(using IconTextButton)
- **`AssetsSidebarTab.vue`**: Refactored to use `MediaAssetSearchBar`

### 4. Utility Usage
- Improved sort logic using `es-toolkit`'s `sortBy`
- Follows project guidelines (CLAUDE.md)

## Technical Details

### History V2 API's create_time
- Cloud backend provides `create_time` (in milliseconds) through History
V2 API
- Enables accurate sorting by creation time
- For input assets, uses existing `created_at` (ISO string)

### Sort Implementation
Uses `es-toolkit`'s `sortBy` in `useMediaAssetFiltering` composable:

```typescript
// Get timestamp from asset (either create_time or created_at)
const getAssetTime = (asset: AssetItem): number => {
  return (
    (asset.user_metadata?.create_time as number) ??
    (asset.created_at ? new Date(asset.created_at).getTime() : 0)
  )
}

// Sort by time
if (sortBy.value === 'oldest') {
  return sortByUtil(searchFiltered.value, [getAssetTime])
} else {
  return sortByUtil(searchFiltered.value, [(asset) => -getAssetTime(asset)])
}
```

## Testing
- ✅ Typecheck passed
- ✅ Lint passed
- ✅ Format passed
