fix: address CodeRabbit review - Vue 3.5 props destructuring and a11y

- Fix inverted pluralization: use single i18n key with {count} param
- Fix text-bold → font-bold (valid Tailwind class) and class ordering
- Replace hardcoded 'Search...' default with i18n t('g.search')
- Remove unused itemSelected i18n key (merged into itemsSelected)
