feat(FR-70): display private tag in Environment page for private images

[yomybaby]

Resolves #2221(FR-70)

Summary

• Add a "Private" tag (red Tag component) next to the status column in the Environment page's image list for images that have the ai.backend.features label containing private
• Extract shared isPrivateImage utility to react/src/helper/image.ts (previously duplicated in ImageEnvironmentSelectFormItems.tsx)
• Add environment.Private i18n key to all 21 language files

Screenshots

Before (Environment page — no Private tag visible)

After

Private images will display a red "Private" tag next to the status badge in the Status column.

Test plan

• Open the Environment page and verify that images with ai.backend.features: private label show a red "Private" tag
• Verify the tag appears alongside the existing "Installed" / "Installing" tags
• Verify in both light and dark themes that the tag is visible and readable
• Verify that non-private images do not show the tag

Pull request overview

Adds a visual indicator in the Environment page image list to help admins identify images that are marked as private (via ai.backend.features containing private), addressing the confusion where such images can be installed but not selectable in “new session” flows.

Changes:

• Display a red “Private” tag in the Environment page image list status column when an image is labeled as private.
• Add environment.Private i18n string across all supported (21) locale JSON files.

react/src/components/ImageList.tsx:55

• isPrivateImage() duplicates the same private-image detection logic already defined in ImageEnvironmentSelectFormItems.tsx. To avoid future drift (e.g., if the label parsing rules change), consider extracting this into a shared helper (e.g., in react/src/helper or a small imageLabels utility) and reusing it from both components.

const ImageList: React.FC<{ style?: React.CSSProperties }> = ({ style }) => {
  'use memo';

  const { t } = useTranslation();
  const [selectedRows, setSelectedRows] = useState<EnvironmentImage[]>([]);
  const [, { tagAlias }] = useBackendAIImageMetaData();
  const { token } = theme.useToken();
