feat(dashboard): provider summary card, free test btn, sidebar order, i18n fix

- sidebarVisibility: move endpoints before api-manager
- en.json: add freeTierProviders/Label/Desc + providerSummaryAll to providers namespace
- page.tsx: apply showConfiguredOnly filter to free tier section (was hardcoded false)
- page.tsx: replace search bar with summary Card containing:
    search (25%) + configured-only toggle + test-all button / dot legend / stats row
    stats show Total / Free / OAuth / API Key configured/total counts
- page.tsx: add batch test button to Free Tier Providers section header
- page.tsx: remove duplicate configured-only toggle from OAuth section header
- page.tsx: import Card component
