Advances are now treated as immediate payments (not pending salary items):
- Auto-creates PayrollRecord + sends payslip email at creation time
- Auto-creates Advance Repayment adjustment for next salary cycle
- Validates worker has unpaid work logs (otherwise use New Loan)
- Requires project selection for cost tracking
- Partial repayment converts advance to regular loan
- Admin can edit auto-repayment amount before payday
- Negative net pay warning in preview modal
