fix: re-declare ARG TARGETARCH in each Dockerfile stage

Browse Source 
Docker automatic platform ARGs are only in scope for FROM instructions.
$TARGETARCH in RUN commands was always empty, so the deadsnakes PPA
conditional never ran and python3.13 could not be found on the Ubuntu
22.04 CUDA base.

### Fixed
- **Dockerfile: `ARG TARGETARCH` re-declared in each stage**: Docker's automatic platform ARGs are only in scope for `FROM` instructions, not `RUN` commands. The `$TARGETARCH` variable in the deadsnakes PPA conditional was silently empty, so the PPA was never added and `python3.13` could not be located on the Ubuntu 22.04 CUDA base. Adding `ARG TARGETARCH` at the top of both the `build` and `runtime` stage bodies fixes the amd64 build.
