Geir O. Jerstad 250ba5e2ea feat: switch to incus-lts and fix lab-tool SSH syntax
- Use incus-lts (6.0.4) instead of latest incus to avoid cowsql build issues
- Re-enable incus on congenital-optimist with LTS version
- Restore incus-admin group membership for users
- Fix missing parentheses in lab-tool SSH module
- This provides stable containerization without build failures
