Add Q as a UI component

[aditya-damerla128]

Requested by @horner.

Summary

Add Q as a first-class component in mieweb/ui.

Q should expose the form/config-generator experience from @mieweb/q through the UI package, separate from the existing AI chat components.

Scope

• Add a new Q component in the UI repo.
• Export Q from a dedicated UI entry point so consumers can import it without treating it as AI chat.
• Reuse the existing @mieweb/q package surface where practical instead of reimplementing Q behavior.
• Include Storybook examples for the Q component.
• Include the expected Q presets:
  • full Twilio agent configuration form
  • agent-only configuration form that hides Twilio/telephony fields
