BUG:Navigation bar hidden when resizing window below desktop breakpoint

### Is there an existing issue for this?

- [x] I have searched the existing issues

### What happened?

## Description
The navigation bar disappears when the application window is resized to smaller tablet or mobile width sizes, making it impossible to access navigation links and menu options.

## Steps to reproduce
- Open the PicToPy application
- Resize the window to a smaller width (approximately below 768px)
- Observe the navigation bar

## Expected Behavior:
The navigation bar should remain visible and accessible at all window sizes, either by:

- Adapting to smaller widths with a responsive layout
- Transforming into a hamburger menu or collapsible navigation
- Maintaining visibility with appropriate spacing adjustments

## Current behavior
