Simplify Docker build and pin dependencies for Artifactory compatibility

- Remove npm registry build arguments from Dockerfile
- Use npm install to leverage host machine's npm config
- Pin vite (6.3.6), rollup (4.50.2), and undici-types (7.12.0)
- Remove all .npmrc files from repo (use machine-level config)
