- Move order form scope to left column only to avoid nested forms
- Place payment/refund forms in right column within same grid row
- Remove transaction delete button - use refunds instead for audit trail
- Simplify transaction history table: show only Date, Payment Method, Amount, and Created By
- Fix form submit buttons to use form attribute for proper association
- Improve visual alignment of two-column layout without empty gaps
This ensures valid HTML (no nested forms), clean financial audit history, and better UX with aligned columns.
