[bugfix] Clear queue button now properly removes initializing jobs from UI (#8203)

## Summary

- Fix: Initializing jobs now properly disappear from UI when cancelled
or cleared
- Add `clearInitializationByPromptIds` batch function for optimized Set
operations
- Handle Cloud vs local environment correctly (use `api.deleteItem` for
Cloud, `api.interrupt` for local)

## Problem

When clicking 'Clear queue' button or X button on initializing jobs, the
jobs remained visible in both AssetsSidebarListView and JobQueue
components until page refresh.

## Root Cause

1. `initializingPromptIds` in `executionStore` was not being cleared
when jobs were cancelled/deleted
2. Cloud environment requires `api.deleteItem()` instead of
`api.interrupt()` for cancellation

## Changes

- `src/stores/executionStore.ts`: Export `clearInitializationByPromptId`
and add batch `clearInitializationByPromptIds` function
- `src/composables/queue/useJobMenu.ts`: Add Cloud branch handling and
initialization cleanup
- `src/components/queue/QueueProgressOverlay.vue`: Fix `onCancelItem()`,
`cancelQueuedWorkflows()`, `interruptAll()`
- `src/components/sidebar/tabs/AssetsSidebarTab.vue`: Add initialization
cleanup to `handleClearQueue()`
