fix: use npm ci instead of npm i in frontend workflows

`npm ci` is the correct command for CI environments as it:
- Installs exact versions from package-lock.json
- Ensures reproducible builds across environments
- Fails if package.json and package-lock.json are out of sync
- Removes node_modules before installing for clean installs
