[Bug]: Migrate AreaChart test cases from enzyme to react testing library

[Copilot]

Overview

This PR migrates the test cases in AreaChart.test.tsx from enzyme to React Testing Library. The migration aligns with the project's testing strategy which prefers React Testing Library over enzyme for all new and migrated tests.

Changes Made

• Replaced enzyme specific imports (mount, ReactWrapper, toJson, etc.) with React Testing Library imports (render, fireEvent, act, etc.)
• Removed the enzyme wrapper in favor of RTL's container-based testing approach
• Converted enzyme's component finding methods to RTL's query methods
• Converted event simulation from enzyme's .simulate() to RTL's fireEvent API
• Simplified snapshot testing
• Added accessibility tests using axe
• Kept the test cases consistent with the original file, ensuring the same functionality is tested
• Used the helper functions and patterns from AreaChartRTL.test.tsx and VerticalBarChart.test.tsx as reference

Testing Approach

• All tests verify the same functionality as the original enzyme-based tests
• Added an accessibility test as per modern best practices
• Used the common testing utilities like getById, getByClass, testWithWait, and testWithoutWait

This change makes our test suite more consistent across the codebase and aligns with the React community's preferred testing approach.

Fixes #34522.

check formatting step is failing

Fixed the formatting issues. I found an extra closing parenthesis on line 344 that was causing a syntax error and also addressed whitespace/indentation issues according to Prettier guidelines. All formatting checks now pass. (7c0d1f5)
