🌱 (test): Selector field exclusion in registry+v1 bundle configuration

[anik120]

Description

PR #2454 implemented the selector field exclusion in the schema generator and generated schema, but there was no explicit validation test demonstrating that users would receive a clear error message if they tried to use it. This PR introduces a test that:

1. Documents the behavior explicitly - Makes it clear through tests that selector is not just omitted, but actively rejected
2. Prevents regression - Ensures future schema changes don't accidentally allow the selector field
3. Validates user experience - Confirms users get a helpful error message rather than silent failure

Test Output

rawConfig: []byte(`{
"deploymentConfig": {
"selector": {
"matchLabels": {
"app": "test"
}
}
}
}`),
expectedErrMessage: `unknown field "selector"`
