bug: Dashboard Docker build fails due to missing tsc command

[srini-abhiram]

Describe the bug

The Docker build for the dashboard fails with the error sh: tsc: not found. This is because the TypeScript compiler is not available in the build environment.

To Reproduce

Steps to reproduce the behavior:

1. Navigate to the dashboard directory.
2. Run docker build -t dashboard-test .

Expected behavior

The Docker image should build successfully locally.

Note on reproduction:
This bug only occurs when NODE_ENV=production is set
(via environment variable, .npmrc with production=true, or --omit=dev flag).

Without this, npm ci installs all 246 packages including devDependencies,
and the build succeeds. With production mode, only 62 packages are installed,
causing tsc: not found.

Steps to reliably reproduce:

1. Navigate to the dashboard directory
2. Add ENV NODE_ENV=production after WORKDIR /app/frontend in Dockerfile
3. Run docker build --no-cache -t dashboard-test .

@srini-abhiram Could you please check if your environment contains the production value in any of these options?

echo $NODE_ENV
npm config get production
cat ~/.npmrc 2>/dev/null

Thanks🙏
