feat: add nonce support to genStyleUtils for CSP compliance

[zombieJ]

Pass CSP nonce to useCSSVarRegister when registering CSS variables. This ensures dynamically generated style tags include the nonce attribute when Content Security Policy is enabled.

Also updated @ant-design/cssinjs dependency to ^2.1.2 and fixed React import.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the styling utility by integrating Content Security Policy (CSP) nonce support, which is crucial for applications with strict security requirements. It ensures that all dynamically injected styles are compliant with CSP rules, thereby preventing potential cross-site scripting vulnerabilities. Additionally, it includes an update to a core styling dependency and a minor refactor of a React import.

Highlights

• CSP Nonce Support: Implemented Content Security Policy (CSP) nonce support within genStyleUtils to ensure dynamically generated style tags include the necessary nonce attribute for enhanced security.
• Dependency Update: Updated the @ant-design/cssinjs dependency to version ^2.1.2.
• React Import Refinement: Adjusted the React import statement in genStyleUtils.ts for better type handling.
• Unit Testing: Added a dedicated test case to validate the correct propagation and application of the CSP nonce to style tags.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• package.json
  • Updated @ant-design/cssinjs dependency from ^2.1.0 to ^2.1.2.
• src/util/genStyleUtils.ts
  • Changed React import from import React, { useMemo } from 'react'; to import type React from 'react'; import { useMemo } from 'react';.
  • Introduced useCSP() hook to retrieve CSP nonce.
  • Passed the retrieved nonce to the useCSSVarRegister function for dynamic style tags.
• tests/genStyleUtils.test.tsx
  • Added a test case to ensure nonce is correctly passed to useCSSVarRegister and applied to generated style tags.

Activity

• The pull request was created by zombieJ to add nonce support for CSP compliance and update a dependency.

Code Review

The pull request successfully adds nonce support to genStyleUtils for CSP compliance, which is a valuable security enhancement. The dependency update for @ant-design/cssinjs is minor and the change to type-only React import is a good practice. A comprehensive test case has been added to validate the nonce functionality.

[gemini-code-assist]

The non-null assertion operator ! on csp.nonce! can be misleading here. The useCSP hook, especially its default implementation useDefaultCSP, can return an object where nonce is undefined. While () => undefined might be handled gracefully by useCSSVarRegister, it's generally better to avoid ! when nullability is possible to improve type safety clarity. Consider passing csp.nonce directly or providing a default if useCSSVarRegister strictly expects a string when the nonce property is present.

Suggested change

	nonce: () => csp.nonce!,
	nonce: () => csp.nonce,
