fix(P14): master key rotation (REQ-129, F12, C-30)

---ci---
project: orca
phase: 14
milestone: v0.12
status: execute
---/ci---

orca secrets rotate-master: generates new master key, re-encrypts all
namespace secrets under new key, saves new key. --dry-run reports
affected namespaces. Atomic per-namespace; automatic rollback to old
key on any failure (C-30). Fixed unused nsKey in get+list (pre-existing
vet issue). Build + vet + tests green.
