Fix Dockerfile frontend build path

[Copilot]

Docker build fails at final stage with "/app/static": not found when copying frontend assets.

Changes

• Dockerfile: Corrected COPY path from /app/static to /app/dist to match Vite's default output directory

# Before
COPY --from=frontend-build /app/static ./wwwroot

# After  
COPY --from=frontend-build /app/dist ./wwwroot

The frontend build stage uses Vite which outputs to dist/ by default. The assetsDir: 'static' config in vite.config.ts creates a subdirectory within dist, not at the root.

Pull Request Overview

This PR fixes a Docker build failure in the final stage caused by an incorrect COPY path for frontend assets. The build was attempting to copy from /app/static when Vite outputs to /app/dist by default.

Key Change:

• Updated Dockerfile COPY command to use the correct Vite output directory (/app/dist instead of /app/static)
