Refactor duplicate toPascalCase implementation in project loader

[jyotish6699]

Description

The project loader currently contains two implementations of the toPascalCase() function in web-app/js/projects.js.

Since JavaScript uses the latest function definition, the second implementation overrides the first one. This creates redundant code and can make maintenance more difficult.

Proposed Solution

• Remove the duplicate implementation.
• Keep a single source of truth for toPascalCase().
• Preserve existing functionality and special-case handling.

Benefits

• Improves maintainability.
• Reduces code duplication.
• Makes the project loader easier to understand.
