ConnorYoh e5a258a648 Dev: redirect bare subpath /app → /app/ when RUN_SUBPATH is set (#6934)
## Problem

With `RUN_SUBPATH=app`, the app is served under base `/app/`. Vite
serves `index.html` at `/app/` and redirects `/` → `/app/`, but a bare
**`/app`** (no trailing slash) returns **404** — so you had to type
`localhost:5173/app/` to load the app. `/app` should work too.

## Fix

A small dev + preview middleware that **301-redirects `/app` → `/app/`**
(query string preserved), so either form loads the app. Only active when
`RUN_SUBPATH` is set; no-op otherwise.

Also routed the vite `base` through the same slash-stripped `runSubpath`
value the middleware uses, so a stray `RUN_SUBPATH=/app/` can't produce
a doubled `//app//` base.

## Verified (dev server + prod build, `RUN_SUBPATH=app`)

| Request | Before | After |
|---|---|---|
| `GET /app` | 404 | **301 → `/app/`** |
| `GET /app?foo=1` | 404 | **301 → `/app/?foo=1`** (query kept) |
| `GET /app/` | 200 | 200 (unchanged) |
| `GET /` | 302 → `/app/` | 302 → `/app/` (unchanged) |

Production build under the subpath still emits `<base href="/app/">` and
`/app/assets/...`. Lint + format green.
