feat: update embedded web API parity

[Morten Barklund (barklund)]

Summary

• Sync embedded payload types with the current assistant embedded API surface, including document options, template source filters, template assembler section field access, and app configuration.
• Add the missing showDeviceLinkQR public wrapper and expose it through the React API hook so component APIs match the generated embedded API.
• Expand the embedded web demos with app configuration, supported template source options, template assembler field access, document generation options, and device-link QR controls.

Replaces #31 because sync/embedded-types is an automation-owned branch that gets reused.

Fixes DXA-3696

Pull request overview

This PR updates the embedded-web package’s public types and demos to match the latest embedded Assistant API surface (template sources/inline templates, forced first-document generation, document generation limits), and adds a missing showDeviceLinkQR wrapper so the component API matches the generated embedded API.

Changes:

• Synced/expanded embedded payload + response types (inline templates, template source options, maxGenerated, device-link response/status).
• Added showDeviceLinkQR action/type wiring and a new public CortiEmbedded.showDeviceLinkQR() wrapper.
• Updated the HTML + React demos to showcase the new configuration and template capabilities.

Looks great I just think some of the types have drifted a bit, probably due to the automatic PR:

• types/api navigate is defined to accept a string but in CortiEmbedded we do still accept an object as well. But the main thing is the in /public-types we have the correct interface
• here we say setInteractionOptions PATCHES, but here the DOCSTRING is slightly contradictory
