feat: add StroyBot app shell with URL routing

One web part replaces the separate stroy-bot-* web parts. The section and
its parameters live in the page query string (?page=objects&projectId=5),
so links can be copied, opened in a new tab and the browser Back button works.

- shared config: site/Dataverse/API addresses, list and table names
- HTTP layer behind IHttpClient so repositories can be unit-tested
- ui-kit AppLayout + Sidebar, placeholder for sections not ported yet
- migration checklist with every feature of the old web parts
- design tokens mirrored from ui-kit instead of 8 copies
