fix: simplify build-and-restart-telegram.sh, drop dead lock/PID file

- Remove unused LOCK_FILE and PID_FILE (odek has its own singleton lock)
- Remove ODEK_TELEGRAM_LOG_FILE env (odek uses config.json for log path)
- cd to PROJECT_DIR before starting bot so cwd is correct
- Replace nohup with exec for cleaner process management
