feat: implement soft delete and force cleanup for webshops

Add comprehensive soft-delete mechanism to prevent data loss and provide better control over shop deletion:

**Database Changes:**
- Add `deleted_at` column to shops table for soft delete tracking
- Update all shop queries to filter out soft-deleted shops
- Create `getDeletedShops()` method to retrieve soft-deleted shops
- Add `forceDeleteShop()` method for permanent deletion with Qdrant cleanup queuing

**API Changes:**
- Update DELETE /api/shops/:id to use soft delete instead of hard delete
- Add GET /api/shops/deleted endpoint to list soft-deleted shops
- Add DELETE /api/shops/:id/force endpoint for permanent deletion
- Fix Qdrant deletion queue foreign key issue that prevented cleanup

**Web UI Changes:**
- Add deleted shops section to /ui/shops page
- Show warning banner with list of soft-deleted shops
- Implement force delete button with confirmation dialog
- Add deleted_at field to Shop type interface
- Update ApiService with getDeletedShops() and forceDeleteShop() methods

**Key Features:**
- Soft-deleted shops are hidden from API but data is preserved
- Force delete permanently removes all data and queues Qdrant cleanup
- Deleted shops show time deleted and custom ID for identification
- Clear warnings about data removal with multi-step confirmation

This resolves the issue where deleted shops were still visible and Qdrant cleanup never occurred due to cascading foreign key constraints deleting the cleanup queue entries.
