fix: show moved account notice in hover card popup

- Add conditional logic to display moved account notice when account.moved is present
- Include link to new account with proper formatting
- Hide follow/unfollow buttons for moved accounts to prevent confusion
- Add localization key 'account.moved_to_short' for hover card context
- Style moved notice to match existing hover card design patterns

Fixes #35623
