Fix flat-rate coat wizard UX, — literal, select caret overlap, and walkthrough modal sizing

- Flat-rate items now default coat type to Custom so Color Name field is immediately visible
- Catalog search blur copies typed text to Color Name when no catalog result was selected
- Item card shows 'No color specified' badge when coat has powder-to-order but no color name
- Color Name label marked required with '(shows on quote)' hint
- Coat name select min-width prevents text overlapping Bootstrap caret arrow
- Remove extra unbalanced </div> from renderSalesFields
- Fix literal &mdash; in quote simple-mode hint (textContent → innerHTML)
- Formula walkthrough modal fixed at 700px so all steps render at identical window size
