Merge branch 'dev' into feat/openwebui-integration

Resolve conflicts by keeping both openWebUi and dev-side registry entries
(integration/widget kinds, creators, docs sitemap). Take dev's next.config
turbopack settings. Reset SQLite migration base to dev's 0040_add_widget_secret;
the integration.creator_id migrations are regenerated for all dialects in a
follow-up commit.
