pacman reads a node's declared packages from the node-engine alone (ADR 0565 clause 6)

The controller's declared-packages mirror ended with its lease: the view no longer falls back to it, the manifest no
longer reads it, and a node whose engine wrote no key is named in the answer (declared_none) instead. The fallback
rows of the view test became the no-key and unreadable-engine cases; no test added.
