fix(refine-ui): align auto save i18n keys

[yasuo72]

Fixes #7185

This PR updates the ShadCN auto-save indicator component and its registry JSON so that
the translation keys match the i18n guide:

• autoSave.loading
• autoSave.success
• autoSave.error
• autoSave.idle

This ensures that when users follow the documented autoSave translations, the
indicator shows the correct translated text instead of raw keys.

Tests:

• pnpm run test -- --scope @refinedev/refine-ui (no tests defined for this package)
• pnpm run test -- --scope @refinedev/antd (previously run while working in this repo)
