fix: commit WordFormatUI source files and update .gitignore for CI

The CI build-ui job uses actions/setup-node@v4 with cache: 'npm', which
requires package-lock.json to compute the cache hash. This file was not
committed, causing "Some specified paths were not resolved, unable to
cache dependencies" error.

Also added node_modules/ and .env to .gitignore to prevent accidental
commits of dependencies and secrets.
