Subject: [PATCH] fix: dvije greske koje su rusile instalaciju

- POSTGRES_PASS generiranje: `tr ... </dev/urandom | head -c 32` puca
  na SIGPIPE (exit 141). Uz `set -euo pipefail` install.sh je tiho
  izlazio prije nego sto je ista instalirao. Zamijenjeno ogranicenim
  citanjem: `head -c 512 /dev/urandom | tr -dc ... | cut -c1-32`.

- docker-compose.yml: guacamole/guacamole:1.5.5 trazi POSTGRESQL_USER,
  a compose je postavljao POSTGRESQL_USERNAME. Kontejner je zavrsavao
  u restart petlji s "FATAL: Missing required environment variables".
