chore(deps): move frontend-only deps out of runtime deps (#4630)

# Summary

This PR moves frontend-only packages from `dependencies` to
`devDependencies` so they are no longer kept in the runtime Docker
image.

The current image runs the server and serves the built `dist/` frontend,
so browser-only libraries used exclusively during frontend build and
in-browser execution do not need to remain in production runtime
dependencies.

# What Changed

- Moved frontend-only packages from `dependencies` to `devDependencies`
- Updated `package-lock.json` to reflect the new dependency
classification

Packages moved include UI and browser-side libraries such as:

- `vuetify`
- `vue`
- `vue-router`
- `pinia`
- `vis-network`
- `vis-data`
- `prismjs`
- `axios`
- `socket.io-client`
- and related frontend-only packages

# Why

While reviewing the Docker image contents, `vuetify` stood out as a
large dependency, around `60 MB` installed, even though it is only used
by the built frontend and is not required by the runtime server.

From there, the same pattern was identified across a broader set of
frontend-only libraries: they were useful for building and running the
UI in the browser, but not needed in the production container that
serves the already-built assets.

# Result

With the current Docker build path, the image size changed from:

- `507 MB` before
- `292 MB` after

That is a reduction of about `215 MiB` (`42%`).
