feat(electron): separate dev/uat build targets with isolated update channels

- Add build.dev.json to override publish.url for dev environment
- Add build:dev and build:uat scripts; each sets its own feed URL
- copy-to-nas.js now accepts env argument; outputs to
  electron-update/{dev|uat}/ locally and on NAS
- docker-compose volume mounts updated to serve from env subdirs
- Remove stale artifacts from electron-update root
