test(ui): run e2e against the minified vite build, not the dev server
The e2e booted the unminified Vite dev server, so production-minification bugs
were invisible to it — exactly how a minifier dropping a bare `void recenter`
reactive read slipped through. Build the app in mock mode and serve the minified
artifact via `vite preview` instead, so the smoke exercises the same bundle the
contour ships. Build to dist-e2e/ (gitignored) so it never clobbers the dist/ the
bundle-size gate measures, and with `--base /` so the SPA-fallback also boots a
subpath like /telegram/ (the production relative base needs the gateway's path
mapping, absent under a plain preview). All 118 specs pass against the build on
both engines, including the hint-recenter spec — confirming the hardened
dependency survives minification.

// Hermetic e2e: Playwright builds the app in `mock` mode (the in-memory fake transport, so the
// smoke needs no backend/gateway/Postgres) and serves the MINIFIED artifact via `vite preview`,
// rather than the dev server. Running against the production-minified bundle is what the contour
// ships, so the e2e now catches minification-only regressions — e.g. a reactive dependency the
// minifier drops — which the unminified dev server silently hid. The build goes to dist-e2e/ so it
// never clobbers the dist/ the bundle-size gate measures.
