fix : added fallback heading creation when project heading not found in modal.js

[tmdeveloper007]

Summary of What Has Been Done

Added a fallback heading creation in web-app/js/modules/modal.js inside the openProjectSafe function. If no heading element (h2, h3, .pet-title, or title/header class) is found in the project content, a synthetic h2 heading is now created and prepended to the content before the info button is injected.

File changed: web-app/js/modules/modal.js

Changes Made

• Added a third !firstHeading check after the two existing heading searches
• Creates an h2 element with a PascalCase version of the project name
• Prepends the heading to .project-content before the info button injection

Impact it Made

• Info button is always injected regardless of project HTML structure
• Users can always access project instructions for projects without headings
• No visual regression for projects that already have headings

Closes #1816
