[Accessibility] [Windows] [Missing Label] - "Muda" logo missing label for screen readers

[ceciliabelem]

Describe the bug
The "Muda" logo on the invite screen lacks an accessible label, causing it to be announced by screen readers as an unidentifiable image or object. This prevents screen reader users from understanding the purpose or identity of the logo, hindering navigation and usability.

Severity: High - This issue prevents screen reader users from understanding the purpose of the "Muda" logo, creating confusion and blocking access to important content or functionality.

To Reproduce

1. Open the Muda platform in a Windows environment.
2. Go to the invite screen using this link: https://muda.cambiatus.io/invite/Pzz98P.
3. Navigate through the page using a screen reader and observe how the "Muda" logo is announced without a proper label.

Expected Behavior
The "Muda" logo should have an accessible label (using the alt attribute or aria-label), so it is correctly identified by the screen reader, allowing users to understand its context and purpose.
