Description

Fixed ESLint configuration to properly apply to all directories in the project and enabled JSX parsing for JavaScript files.

Changes Made:

1. Broadened File Pattern: Changed files: ["src/**/*.{js,jsx,ts,tsx}"] to files: ["**/*.{js,jsx,ts,tsx}"] to match all JS/TS files in any directory within the project.

2. Enabled JSX Parsing: Added ecmaFeatures: { jsx: true } to parser options so ESLint's default Espree parser can understand JSX syntax.

Root Cause:

• The original file pattern only matched files in the root-level src/ directory
• Files in other directories (e.g., Hyperswitch-React-Demo-App/src/) had no ESLint configuration applied
• JSX parsing was not explicitly enabled

Fixes #1448

How did you test it?

Ran ESLint on the project and verified it correctly parses JSX files in all directories without errors.
