fix(nginx): stop stripping the /api/ prefix on proxy_pass

[obrien-k]

Summary

Both proxy.nginx.conf and proxy-tls.nginx.conf proxy_pass to the api backend with a trailing slash on the URL (proxy_pass http://api:8080/;). In nginx, that rewrites away the matched location /api/ prefix before forwarding — so a request to /api/auth/login reaches the backend as /auth/login.

api mounts every route under /api/* internally:

src/app.ts:144:  app.use('/api/auth', authRouter);
src/app.ts:145:  app.use('/api/users', userRouter);
... (all routes, confirmed at the v0.7.0 tag currently pinned in docker-compose.yml)

So as currently pinned, every request through this proxy config would 404 against the real api routes — nginx needs to forward the full /api/... path unchanged.

Change

Drop the trailing slash on both proxy_pass directives so the full request URI is forwarded as-is.

Test plan

• Confirmed api's route mounting at the v0.7.0 tag via git grep "app.use('/api" — all routers expect the /api/ prefix
• Smoke-test end-to-end against a running stack (not yet done here — static analysis only)
