feat(05-08): add cloud tree components and getCloudFolders API function

- Add getCloudFolders(provider, folderId) to api/client.js (GET /api/cloud/folders/{provider}/{folderId}) - Create CloudProviderTreeItem.vue: lazy-load folder tree per connection, providerIconColor computed, expand/collapse arrow, loading/error states - Create CloudFolderTreeItem.vue: recursive folder tree node with is_dir expand arrow, lazy-load children, depth padding
