feat(ui): render Provider Settings from a store

initKeySetup keeps the setup requests, the ChatGPT OAuth flow, the pasted
field values and the dialog's keyboard, and publishes the POWER UP chip,
the dialog, its key rows and the status line to the gev-provider-settings
store. ProviderSettingsView renders them and sends clicks and typing to
the connected owner; in Cyber the chip is teleported into the top
toolbar. A successful save renders the rows afresh so no field keeps a
key, and the status line announces a repeated message again. The voice
action opens and closes the dialog through the same controls.
