fix(frontend): migrate dev Dockerfile from Docker to UBI image

[mprpic]

Replace node:20-alpine with registry.access.redhat.com/ubi9/nodejs-20 for consistency with other components. Remove apk install of libc6-compat, python3, make, and g++ as the UBI nodejs-20 s2i builder image already includes them.

Walkthrough

Frontend Docker development image updated: base changed to a Red Hat UBI9 Node.js image, Alpine-specific package steps removed, root user and working directory ensured, telemetry disabled, port 3000 exposed, and container CMD installs deps then starts the dev server.

Changes

Cohort / File(s)	Summary
Frontend Development Container components/frontend/Dockerfile.dev	Base image changed from node:20-alpine to registry.access.redhat.com/ubi9/nodejs-20:1. Removed Alpine package installs and related RUN lines. Added USER 0, ensured WORKDIR /app, kept ENV NODE_ENV=development, added ENV NEXT_TELEMETRY_DISABLED=1, EXPOSE 3000, and CMD ["sh", "-c", "npm ci && npm run dev"].

Inline comments:
In `@components/frontend/Dockerfile.dev`:
- Line 4: The Dockerfile contains a "USER 0" directive that forces the container
to run as root; either remove or replace it with the non-root user provided by
the UBI image (UID 1001) so the container runs as a non‑root user, or if running
as root is required for development, leave "USER 0" but add a clear comment next
to the "USER 0" line explaining the reason (e.g., volume permission workarounds)
and that it is only for dev; update any related build/run docs to reflect the
chosen approach and ensure tests still pass when using USER 1001 (check startup
scripts and file permissions).
- Line 2: The Dockerfile base image is unpinned; update the FROM line in
components/frontend/Dockerfile.dev (the FROM instruction referencing
registry.access.redhat.com/ubi9/nodejs-20) to a specific tag (for example change
to registry.access.redhat.com/ubi9/nodejs-20:1 or another chosen
timestamped/major tag) so builds are reproducible; ensure you commit the updated
FROM value and verify the image tag chosen matches the desired compatibility
level.
