feat: task 1.3 vite dev proxy + tsconfig hardening

Same-origin dev proxy via Vite's server.proxy:
- /api/*       -> ${VITE_DEV_DIRECTUS_URL}/*   (Directus REST + GraphQL)
- /ws-business -> ws://.../websocket           (Directus business-plane WS)
- /ws-live     -> ${VITE_DEV_PROCESSOR_WS_URL} (Processor live WS, Phase 1.5)

WS proxy targets derive ws:// scheme from the http(s) Directus URL.
loadEnv reads VITE_DEV_* overrides; sensible localhost defaults.

tsconfig.app.json: noUncheckedIndexedAccess + noImplicitOverride.

.env.example documents the two override vars; .env.local is gitignored
via the existing *.local pattern.

README "Local dev" section: proxy table + override instructions + port
collision workaround.

Deviation: spec called for .env.dev.example/.env.dev.local but Vite's
dev mode is "development" not "dev", so mode-specific files would be
.env.development.* and Vite wouldn't auto-load .env.dev.local. Switched
to the standard Vite .env.example/.env.local convention. Documented in
the task's Done section.

Plus: backfill 1.2 commit SHA (9918418) in its Done section.

+`vite.config.ts` switched to the function form, reads env via `loadEnv(mode, process.cwd(), 'VITE_')`, exposes three proxy routes:
+
+- `/api/*` → `${VITE_DEV_DIRECTUS_URL}/*` (default `http://localhost:8055`), strips the `/api` prefix.
+- `/ws-business` → derived `ws://...` from the Directus URL, rewrites to `/websocket`.
+- `/ws-live` → `${VITE_DEV_PROCESSOR_WS_URL}` (default `ws://localhost:8081`), strips the `/ws-live` prefix.
+
+`tsconfig.app.json` gains `noUncheckedIndexedAccess: true` and `noImplicitOverride: true`. The `@/*` path alias was already set up in 1.2 (deviation noted there).
+
+`.env.example` (committed) documents the two proxy override env vars; `.env.local` (already gitignored via the existing `*.local` pattern) is the developer's actual values file. README "Local dev" section rewritten with the proxy table and override instructions.
+
+**Deviation from spec:** the spec called for `.env.dev.example` / `.env.dev.local` but Vite's mode for `pnpm dev` is `development` (not `dev`), so mode-specific files would be `.env.development.local` and Vite wouldn't auto-load `.env.dev.local` at all. Switched to the standard Vite convention `.env.example` (committed docs) + `.env.local` (auto-loaded in any mode, gitignored). Cleaner and matches Vite's actual behaviour.

 ## Local dev
 
-The Vite dev proxy (Phase 1.3) routes `/api`, `/ws-business`, `/ws-live` to the appropriate local services so the SPA dev experience matches the stage/prod reverse-proxy topology under one origin. Until 1.3 lands, the SPA runs standalone.
+The Vite dev server (`pnpm dev` on `:5173`) proxies three path namespaces to local services so everything runs same-origin — the same topology stage/prod gets via Traefik, no CORS workarounds needed.

+
+Override per-developer by copying `.env.example` to `.env.local` and editing — Vite auto-loads `.env.local` in any mode and the values flow into `vite.config.ts` via `loadEnv`.
+
+If the dev port `5173` collides with another Vite app, run with `VITE_PORT=5174 pnpm dev` (or pin a different port in `vite.config.ts`).
