Adds cloudcommander and it-tools .env files. it-tools' private .env
had two real domains (it-tools.local.thesabear.net,
it-tools.thesabear.net) that the public compose file doesn't
reference at all, so dropped along with the unused DOCKER var.
This completes .env/.env.secrets.ctmpl coverage across every
category in stacks/ (identity-and-security, platform, media,
productivity, dev-tools) - every var cross-checked against its
actual public compose file throughout.
