feat: Add system CPU, temperature, and RAM to Telegram reports

- Split CPU display into App CPU (containers) and System CPU (host)
- Added CPU temperature from hwmon (cross-platform)
- Added system RAM usage alongside app RAM
- Added get_container_stats() to telegram script for proper aggregation
- Fixed build_report() to aggregate all containers instead of head -1
