fix(demo): rewrite deployment scripts and test suite for 16-service stack

Rewrite demo-stack.sh, demo-test.sh, validate-all.sh, and all test
files to match the current 16-service stack reality.

Key changes:
- demo-stack.sh: full rewrite with deploy/stop/restart/status/smoke/summary
- demo-test.sh: fix hardcoded kneldevstack filter to use $COMPOSE_PROJECT_NAME,
  raise volume threshold from 10 to 15, remove curl dependency (use /dev/tcp),
  fix security compliance check for Dockhand direct socket mount
- validate-all.sh: remove port 4005 check (internal only), add missing env
  var validation (TA_PASSWORD, ELASTIC_PASSWORD, GF_*, PIHOLE_WEBPASSWORD)
- integration tests: fix container names, add TubeArchivist companion tests
- e2e tests: use correct project-relative paths, dynamic port lists from env
- Add fix-and-ship.sh as convenience wrapper for demo-stack.sh
- Remove stale tmp_template.yml
