fix(supervisor): copy retry-prisma-generate.mjs into the image build (#4157)

## What

Adds the missing `COPY scripts/retry-prisma-generate.mjs` to the
supervisor `Containerfile` builder stage, before `RUN pnpm run
generate`.

## Why

The `generate` scripts in `internal-packages/database` and
`internal-packages/run-ops-database` shell out to
`scripts/retry-prisma-generate.mjs`. The supervisor build never copied
that file into the image, so `pnpm run generate` failed:

```
@internal/run-ops-database:generate: Error: Cannot find module '/app/scripts/retry-prisma-generate.mjs'
```

This is the same failure class as #4156 (webapp Dockerfile). The
supervisor `Containerfile` is the **only other** build file that runs
`pnpm run generate` — the coordinator / docker-provider /
kubernetes-provider Containerfiles don't, so this completes the fix.

## Verification

Local `docker build` of the supervisor `Containerfile` builder target —
result appended below once the build completes.
