Fix Docker build failure: copy vendor's scripts/ directory

The Dockerfile COPYs scripts/vpn-diagnostics.sh and
scripts/dns-whitelist.sh into the image, but the vendor-file-copying
step in both asterisk.sh and asterisk-do.sh never copied (or
downloaded, in the GitHub-fallback branch) that scripts/ directory —
only Dockerfile, entrypoint.sh, coturn-entrypoint.sh, and the
management script. Every real install hit "docker compose up -d
--build" failing with:

  failed to compute cache key: ... "/scripts/dns-whitelist.sh": not found

Confirmed live on a deployed droplet. vendor/easy-asterisk/scripts/
already has both files — this was purely a missed copy step, not a
vendoring gap. Fixed in both files identically (mkdir scripts/, copy
or curl both scripts, chmod +x alongside the existing executables).

Verified at the filesystem level: after a full install run, both
files land in the build context with correct executable permissions,
resolving the exact COPY instructions that were failing. Full
docker build verification wasn't possible in this sandbox (a separate,
unrelated network restriction blocks pulling the ubuntu:24.04 base
image here), but the missing-file root cause is directly fixed.
