fix(docker): pass placeholder DATABASE_URL/AUTH_SECRET during web build

Setting the route's `dynamic = "force-dynamic"` only stops Next from
calling the GET handler — not from evaluating the route module. The
bundled route.js inlines lib/db.ts's top-level
createClient(env.DATABASE_URL); next build's "Collecting page data"
pass imports the bundle, env access fires, and Zod throws because
the build container has no DATABASE_URL.

Same story for AUTH_SECRET via actions/auth.ts.

Export both as placeholders inside the RUN layer. pg.Pool is lazy
(stores URL, only connects on first query) and AUTH_SECRET only
matters at sign/verify time, so neither placeholder runs during
build. Each Dockerfile RUN is its own shell — nothing leaks into
the runtime image.
