Fix stock import UI bugs: dead code, fragile data attr, double-click, silent duplicates

- Remove unused stockMappingsCache variable (dead code after selectStockMappingRow removal)
- Move data-description from SVG to button element for reliable access
- Add disabled guard on bulk add/ignore buttons to prevent duplicate requests
- Return explicit error in UpsertIgnoreRule when rule already exists
