Enhance PaidUntilBadge component to support pending payment review status

- Updated the PaidUntilBadge component to accept a new `pendingReview` prop, indicating if a payment is awaiting admin confirmation.
- Modified the rendering logic to display a warning badge when a payment is under review, providing users with a neutral status instead of a negative one.
- Updated relevant components in billing and dashboard routes to pass the new `pendingReview` prop based on the active payment request status.
- Added internationalization support for new labels related to the pending review status in both English and Russian.
