Which component is affected?

Prowler UI

Cloud Provider (if applicable)

Not applicable

Steps to Reproduce

1. Open the provider wizard in the Prowler UI.
2. Select a provider and continue through the credentials and connection test steps.
3. Exercise the wizard navigation or update an existing provider.
4. Observe that the modal can repeatedly re-render or fail to advance reliably, and update mode can close before the launch step.

Expected behavior

The provider wizard should keep stable state while form controls publish footer updates, advance deterministically through the connection test, and show the launch step when appropriate.

Actual Result with Screenshots or Logs

The wizard can enter a modal render/update loop because form steps publish semantically unchanged footer configurations containing newly created callbacks. In update mode, a successful connection test closes the modal instead of reaching the launch step.
