🔄 Sync entrypoint and setup scripts from current template 🔄

Ran the AI.md template-update runbook: synced .env.scripts and
Dockerfile ARGs to the current template, regenerated entrypoint.sh
and setup/*.sh from the template, then cleaned up now-dead
DEFAULT_FILE_DIR/DATA_DIR/CONF_DIR/TEMPLATE_DIR references left in
the Dockerfile after the template-files concept was retired.

- .env.scripts: dropped DEFAULT_FILE_DIR/DATA_DIR/CONF_DIR/TEMPLATE_DIR,
  ssmtp -> msmtp, license MIT -> WTFPL, ENV_PULL_URL value updated
- Dockerfile: removed now-unused DEFAULT_FILE_DIR/DATA_DIR/CONF_DIR/
  TEMPLATE_DIR ARG declarations (3 stages) and the mkdir referencing
  them; PACK_LIST ssmtp -> msmtp
- rootfs/usr/local/bin/entrypoint.sh: regenerated from template —
  CONTAINER_NAME set to "rust", safer grep -- usage, exec/shell
  argument handling fixed to not swallow args when none given
- rootfs/usr/local/etc/docker/functions/entrypoint.sh: regenerated
  from template
- rootfs/root/docker/setup/00-init.sh: regenerated; dropped dead
  template-files cleanup block
- rootfs/root/docker/setup/01-system.sh: regenerated (boilerplate only)
- rootfs/root/docker/setup/02-packages.sh: regenerated (boilerplate only)
- rootfs/root/docker/setup/03-files.sh: regenerated — dropped
  template-files mirroring, added /tmp/usr handling
- rootfs/root/docker/setup/04-users.sh: regenerated (boilerplate only)
- rootfs/root/docker/setup/06-post.sh: regenerated (boilerplate only)
- rootfs/root/docker/setup/07-cleanup.sh: regenerated (boilerplate only)

Note: rootfs/root/docker/setup/05-custom.sh was NOT regenerated —
it holds hand-written Rust toolchain install logic, not template
boilerplate; the runbook's blind regenerate would have destroyed it.
