routes: fetch current data, merge in JS, write back as data::jsonb.

Phase 1: user picks which surfaces their product needs (Web App,

horizontal card gallery with mini visual previews of each UI library.
Lock in confirms the choice; locked themes are saved to DB and shown
to the AI coder. Surfaces and themes stored in fs_projects.data.
