[Shopify] Fix Shopify refund/return deletion wiping all lines (#7320)

## Summary
- **Bug 626081**: Deleting a single Shopify refund or return header
deletes lines for **all** refunds/returns, not just the deleted one
- **Root cause**: `SetRange("Field Name")` in `OnDelete` triggers was
called without a value parameter, which clears the filter instead of
setting it — causing `DeleteAll` to wipe the entire line table
- **Fix**: Pass `Rec."Refund Id"` / `Rec."Return Id"` as the second
parameter to `SetRange` in 3 locations across 2 files
