Add progress descriptions to install.sh for slow connections

Each major install step now shows what it does and how long to expect:
- System update: 2-10 min on fresh servers
- Security tools: under a minute
- Docker: 1-3 min (largest download)
- Clone: a few seconds

Updated guide.md terminal output to match.
