Fix output validation tests to work with plan command

- Removed assertions that check resource IDs (not available during plan)
- Kept resource_pool_names output test (based on variables)
- Added verification for expected resource group keys in output
- Fixes: "Unknown condition value" error in verify_outputs test

Resource IDs are only known after apply, so they can't be validated
during plan phase. The remaining tests verify output structure using
variable-based data that is available during plan.
