cmdio: wrap promptui so callers stop importing it directly

[pietern]

Summary

• Add cmdio.SelectOptions/RunSelect and cmdio.PromptOptions/RunPrompt as a neutral surface around promptui.
• Migrate 4 RunSelect callers and 6 Prompt callers across cmd/auth, cmd/configure, and libs/databrickscfg. After this change, promptui is only imported under libs/cmdio, making a future swap of the prompt library a one-package change.
• Behavior is unchanged.
