PR Title:
Ensure FirstName and LastName Follow Pascal Case in QuickGrid Component

Description:
This PR updates the Person record in the QuickGrid component to ensure that firstName and lastName follow Pascal Case as FirstName and LastName. This change improves code consistency and aligns with standard C# naming conventions.

Changes:

• Renamed firstName to FirstName and lastName to LastName in the Person record.
• Updated all references in the QuickGrid component to use Pascal Case.
• Ensured filtering and styling logic correctly references FirstName instead of firstName.

These changes enhance readability and maintainability while following best practices in .NET development.
