fix(nix): fix GHC 9.10.3 interface-file crash and binary name

Browse Source 
Generated.Types imports 119 modules, pushing the combined .hi read past
a ~287 MB binary-deserialization limit in GHC 9.10.3. Fix by adding a
nixpkgs overlay that patches the inter-hub-models derivation: replaces
Generated/Types.hs with a thin TypesPart1/TypesPart2 re-export wrapper
after build-generated-code runs, and adds the two split modules to the
cabal exposed-modules list.

Also fix the production binary name from /bin/App to /bin/RunProdServer
in deployment.yaml and RUNBOOK.md (the IHP NixSupport build produces
RunProdServer, not App). Switch packages.docker to IHP's built-in
unoptimized-docker-image which already uses the correct binary path.
