fix(aionui): Use production-only deps for runtime, hoist transitive deps

Replace full node_modules copy with production-only FOD (mirrors
the upstream Dockerfile pattern), reducing package output from
~6.9 GB to ~1.3 GB.

Hoist @sentry/node to top-level node_modules so Electron's
require() resolution can find it. Bun nests transitive deps
inside .bun/ but Electron resolves from the realpath, requiring
the dependency to be accessible from the walked-up directory
chain.
