ci(web): Phase P6 — vite build in PR CI + headless E2E gate on trunk publishes (#1445)

- ci.yml: build step (vite build via turbo) runs on every PR pipeline after test
- publish.yml: e2e step boots the gateway from built dist (HOME/cwd-isolated
  throwaway PGlite) and runs the Playwright suite headless inside
  mcr.microsoft.com/playwright:v1.58.2-noble against the SPA bundle served
  exactly as production serves it; both kaniko publishes now gate on e2e
- serve-spa.ts: strip query strings before asset resolution; immutable
  cache-control for hashed assets (onSend hook); e2e spec covers both
- e2e suite hardened: globalSetup seeds admin+member through real
  bootstrap/better-auth APIs (Origin header for CSRF), loginAs waits for the
  post-login redirect (fixes 27-skipped race), stale #152-era assertions
  rewritten to the current command-driven UI, strict-mode violations fixed
  with level-1 heading queries and .or() auto-retrying locators
- verify-release mirrors the new build stage; playwright artifacts ignored

+  # real gateway on the embedded PGlite path (no DATABASE_URL, no services)
+  # serving the built SPA bundle via WEB_DIST_DIR — the exact serving path the
+  # gateway image ships (docker/gateway.Dockerfile sets WEB_DIST_DIR to the
+  # baked bundle), which keeps #1407's parity guarantee: the image build steps
+  # below depend on this gate, so a bundle that fails E2E never publishes.
+  #
+  # Image pinned to the @playwright/test version in pnpm-lock.yaml so the
+  # image's bundled browsers match the workspace driver exactly (bump the two
+  # together). The step installs nothing: it reuses the workspace node_modules
+  # from `install` and the dist outputs from `build` — the gateway's runtime
+  # dependency path is pure JS/WASM (PGlite is WASM, postgres-js is pure JS),
+  # so the alpine-installed modules run unchanged under this glibc image.
+  # depends_on publish-next-npm per the #1411 serialization invariant: this
