- Add run.sh: restarts all containers
- Update restore-db.sh: auto-selects latest dump, terminates active connections before restore
- Add .cursor/commands.json: Cursor commands (init, run, backupFromProd, restoreToLocal)
- Add .vscode/tasks.json: VSCode tasks for running scripts
- Add .vscode/launch.json: launch configurations for restarting server
- Remove play-life-backend/env.example (unified .env in root)
