fix(ui): use i18n for live preview "Open in new window" tooltip (#16038)

The "Open in new window" title attribute in the live preview toolbar was
hardcoded in English. Replace it with the existing `openInNewTab`
translation key, which is already translated in all 44 supported
languages.

Thank you for the PR! Please go through the checklist below and make
sure you've completed all the steps.

Please review the
[CONTRIBUTING.md](https://github.com/payloadcms/payload/blob/main/CONTRIBUTING.md)
document in this repository if you haven't already.

The following items will ensure that your PR is handled as smoothly as
possible:

- PR Title must follow conventional commits format. For example, `feat:
my new feature`, `fix(plugin-seo): my fix`.
- Minimal description explained as if explained to someone not
immediately familiar with the code.
- Provide before/after screenshots or code diffs if applicable.
- Link any related issues/discussions from GitHub or Discord.
- Add review comments if necessary to explain to the reviewer the logic
behind a change

### What?

Replace hardcoded English string "Open in new window" with the existing
`openInNewTab` i18n translation key in the live preview toolbar.

### Why?

The tooltip stays in English regardless of the admin panel language
setting. All other strings in this component already use the
`useTranslation` hook.

### How?

Changed `title="Open in new window"` to
`title={t('general:openInNewTab')}` in
`packages/ui/src/elements/LivePreview/Toolbar/Controls/index.tsx`. The
`openInNewTab` key already exists in all 44 supported languages — no new
translations needed.
