refactor(webserver): extract SPA dist serving to the frontend-static fallback seat

The webserver's built-in static dist serving becomes a single-owner fallback
seat (registerFallback/applyIndexTaps); the SPA server moves to the new
@deepseek-ai/dsh-frontend-static plugin so the composing application owns its
dist as composition, not carrier config. distIndex leaves the webserver
schema; unclaimed fallback answers 404.

## `ctx.httpServer` — `HttpServerService`
The web-shape HTTP carrier service. Activation listens immediately (route registration order carries no request-facing semantics: named routes are composed to be disjoint, and the static dist fallback answers anything not yet claimed during the boot window). A listen failure throws out of init — a FAILED fiber the boot's fail-loud sweep reports.
