Fix missing tutorial progress badges in My Projects grid view

[Copilot]

Tutorial progress badges (e.g. "3/5", "6/6") shown on project cards in the home screen carousel were not appearing in the ScriptManagerDialog grid view ("View All").

Root cause

The grid view in scriptmanager.tsx rendered ProjectsCodeCard without computing or passing tutorialStep/tutorialLength props. The list view in the same file and the home screen carousel both correctly derived these from header.tutorial and header.tutorialCompleted.

Changes

• webapp/src/scriptmanager.tsx — Added tutorialStep and tutorialLength computation in the grid view map, matching the existing pattern in the list view, and passed them to ProjectsCodeCard:

const tutorialStep =
    scr.tutorial ? scr.tutorial.tutorialStep
        : scr.tutorialCompleted ? scr.tutorialCompleted.steps - 1
            : undefined;
const tutorialLength =
    scr.tutorial ? scr.tutorial.tutorialStepInfo.length
        : scr.tutorialCompleted ? scr.tutorialCompleted.steps
            : undefined;

return <ProjectsCodeCard
    ...
    tutorialStep={tutorialStep}
    tutorialLength={tutorialLength}
/>
