fix: never commit package-lock.json, clean install in update.sh, bump v0.5.0

package-lock.json generated on Windows includes win32 rollup binary but
not linux-x64-gnu, breaking the frontend build on the server.

- Add package-lock.json to .gitignore and remove it from git tracking
- update.sh: rm -rf node_modules + package-lock.json before npm install
  so the server always generates a platform-correct lock file from scratch
- update.sh: remove --silent from build steps so errors are visible
- .gitignore: fix stale whm/cpanel dist paths → nixserver/nixclient
