[变更性质] feat(frontend)

[新增功能] round3 页面组件全量迁移 shadcn-svelte（12 页面 + Modal/DatasetWizard/DatasetCard/Status）
[实现方案] .btn→Button、.banner→Alert、table.data→Table.Root、.badge→Badge、.tabs→Tabs.Root、.metric-card/form.card→Card.Root；ProjectStrategyTab div 配对修复
[影响范围] src/pages/*.svelte、src/components/*.svelte
