fix: sync topsql filter state with url

[yibin87]

Summary

• sync TopSQL filter dropdown state with the URL so links can restore instance, limit, group by, and order by
• make the shared query param hook react to URL changes instead of caching stale search state
• add TopSQL Cypress coverage for URL updates and URL-based filter restoration

Testing

• pnpm -C ui exec prettier --write packages/tidb-dashboard-lib/src/hooks/useQueryParams.ts packages/tidb-dashboard-lib/src/apps/TopSQL/pages/List/List.tsx packages/tidb-dashboard-for-op/cypress/integration/topsql/topsql.spec.ts
• pnpm -C ui exec eslint packages/tidb-dashboard-lib/src/hooks/useQueryParams.ts packages/tidb-dashboard-lib/src/apps/TopSQL/pages/List/List.tsx packages/tidb-dashboard-for-op/cypress/integration/topsql/topsql.spec.ts --format unix
• pnpm exec tsc -p tsconfig.json --emitDeclarationOnly false --outDir /private/tmp/tidb-dashboard-lib-tsc
