fix(P19): sudoers hardening — remove apt-get/dpkg (REQ-134, F22)

---ci---
project: orca
phase: 19
milestone: v0.12
status: execute
---/ci---

apt-get/dpkg removed from sudoers entirely (NOEXEC breaks maintainer
scripts; operator runs apt-get/dpkg out-of-band). Only pct + qm remain
(both NOEXEC). Tests updated. Build green.
