- Fixed crash: pagination used `total_pages` key but Pagination class returns `last_page`
- Board offers index: card-based layout with status indicators, usage counts, branch
  names (joined), days-until-expiry warnings, and stat summary at top
- Board offers form: two-column layout with live preview sidebar that shows real-time
  calculation examples, date validation warnings, and contextual help
- Model search now joins branches table and counts payment_request usage per offer
