Matt c70eb1f945 fix(docker): merge prod deps into standalone node_modules (not replace) ...

Replacing the Next standalone node_modules broke turbopack's externalized-
module resolution: the standalone tree is a matched set with the turbopack
server chunks, resolving externals (better-auth, postgres, pino, minio, ...)
by hashed id. With it replaced, every route using them 500'd with
"Failed to load external module <pkg>-<hash>" — confirmed on prod, while
`node .next/standalone/server.js` with the intact tree serves GET / (307)
and /api/health (200) cleanly.

So keep the standalone tree intact and MERGE the complete hoisted prod tree
in with `rsync --ignore-existing`: it adds the custom server's missing CJS
requires (socket.io closure: accepts/ws/engine.io/cors; drizzle-orm/index.cjs)
and skips everything the trace already provides — and tolerates the trace's
pnpm symlinks, where COPY/cp/tar/fs.cpSync all error on symlink-vs-dir.

Validated end-to-end on a host assembly of (intact standalone + merged prod
deps + the polyfilled server bundle): GET / → 307, /api/health → 200, zero
"Failed to load external module", zero MODULE_NOT_FOUND, server listening.
rsync --ignore-existing merge semantics verified in node:20-alpine.
