feat(FR-2915): add showOpen/showCreate/showRefresh buttons to BAIVFolderSelect

[agatha197]

Resolves #7467 (FR-2915)

Summary

Adds the three action-button props (showOpenButton, showCreateButton, showRefreshButton) from the legacy react/src/components/VFolderSelect.tsx onto the shared BAIVFolderSelect fragment in backend.ai-ui, and wires them in both modes of DeploymentAddRevisionModal.

• BAIVFolderSelect
  • New boolean props render a Space.Compact with up to three buttons next to the select.
  • Open: writes the selected folder UUID (local id, via toLocalId when valuePropName === 'id') to the folder URL search param (react-router-dom's useSearchParams — mirrors useFolderExplorerOpener).
  • Create: opens FolderCreateModalV2 (cross-package import, same pattern as BAIDynamicStepInputNumber) pre-filled with usage_mode: 'model'. On success the paginated query refetches under a transition.
  • Refresh: re-runs the paginated query via the existing useFetchKey/startRefetchTransition plumbing.
• Storybook
  • Documents the three new props in the BAI-Specific Props table.
  • Adds WithActionButtons story.
• i18n
  • Adds comp:BAIVFolderSelect.OpenFolder, CreateANewStorageFolder, Refresh to all 21 backend.ai-ui locale files, reusing wording from the main resources/i18n translations where they already exist.
• DeploymentAddRevisionModal
  • Both BAIVFolderSelect usages (preset and advanced modes) now pass showOpenButton showCreateButton showRefreshButton.

Stacked on top of #7465 (FR-2914 — scope add-revision model folder picker to the current project).

Test plan

• Storybook Fragments/BAIVFolderSelect WithActionButtons story renders the three buttons next to the select.
• In DeploymentAddRevisionModal (preset and advanced modes):
  • Refresh button re-runs the paginated query.
  • Create button opens FolderCreateModalV2; creating a new model folder refetches and the new folder appears in the list.
  • Open button is disabled when no folder is selected; once selected, clicking sets ?folder=<uuid> so the explorer opens that folder.
• All 21 locale files include the three new keys.
