fix(import): preview the parsed cost as linked in the review modal

During the per-item import review the booking isn't saved yet, so the Costs section showed an empty 'Create expense' even though a linked cost will be created on save. Show the parsed price (amount + category) as the pending linked expense so the user can verify it up front. Reuses existing i18n keys.
