Radio buttons in the Batch Pay modal let admin choose between:
- "Until Last Paydate" (default): splits at last completed pay period
- "Pay All": includes all unpaid work regardless of pay schedule
Preview re-fetches when mode changes. Workers without teams are
included in Pay All mode (skipped in schedule mode as before).
