fix(extensions-library): add setup hooks for anythingllm and flowise

Both services require secrets via compose :? syntax but had no mechanism
to auto-generate them. Add env_vars declarations to manifests and
setup.sh scripts that generate required secrets on first install.

- anythingllm: ANYTHINGLLM_JWT_SECRET, ANYTHINGLLM_AUTH_TOKEN
- flowise: FLOWISE_USERNAME (default: admin), FLOWISE_PASSWORD
