Build the new Svelte client (client_v2) in CI, bake it into the Docker
image alongside the legacy React client, and serve it by default. Set
SPOOLMAN_LEGACY_CLIENT=TRUE to fall back to the old client.
SinglePageApplication is generalized to serve either client: the React
client keeps its index.html + base-path rewriting, while the Svelte
client uses a 200.html SPA fallback, serves prerendered per-route pages,
and serves relative-path assets verbatim. The tweaked-HTML store is moved
off self.html, which StaticFiles uses as its HTML-mode flag.
The Playwright frontend suite targets the React DOM, so it's pinned to
the legacy client via SPOOLMAN_LEGACY_CLIENT for now.

Add a browser-driven integration suite (tests_frontend/) that runs against
the real production image + PostgreSQL and drives the UI with Playwright:
a smoke test that navigates every page via the sidebar with no console
errors, and a CRUD test that creates a vendor -> filament -> spool entirely
through the UI. Wired up as `poe itest-frontend` and a new `test-frontend`
CI job (reusing the image built for the backend tests, gating releases).
Navigation goes through real UI buttons (language-independent link targets)
and the app language is forced to English so label matchers are stable
regardless of the runner's browser locale.
This immediately caught a real regression: Starlette 1.3.1 (pulled by a
recent dep bump) removed the `method` kwarg from FileResponse, so
SinglePageApplication 500'd on every static asset and the whole UI was dead.
Drop the removed kwarg — Starlette now derives HEAD handling from the scope.
