i18n: translate PlaylistModal to Spanish

- Translated modal titles (new/edit/add to playlist)
- Translated form labels and placeholders
- Translated buttons (create, save, cancel, delete)
- Translated track count and playlist count labels
- Added missing translation keys for actions (add, create, deleteConfirm)
- Used get(t) in $derived() to avoid PostCSS extraction issues
