Summary

Follow-up to #38705.

This PR applies the repository-wide Vite+ vp fmt baseline after the formatter configuration landed.

• Format 6,210 frontend, CLI, E2E, package, and Node.js SDK files from the latest main.
• Align the newly added packages/dify-ui ESLint config with the Oxfmt boundary: disable formatter-covered/conflicting rules while preserving strict semantic, React, accessibility, and Tailwind validation.
• Fix formatter-sensitive ESLint and TypeScript suppression placement without changing runtime behavior.
• Re-enable the CI format check, frontend contract generation, ESLint autofix, and vp fmt autofix steps that were deferred in chore: migrate formatting to vp fmt #38705.

The changes remain split into a formatting commit and a small migration-completion commit.

No associated issue was provided.
