v221 ⑦ public views: node name prefers the public remark

buildProbeNodeView now sources its 'name' from probeDisplayName:
the node's public remark (probe_meta.public_remark) when non-empty
after trimming, else the node name as before. Contract field name
unchanged, theme packages untouched, both audiences (anonymous and
admin frames share the builder); the panel's internal node list is
a different surface and keeps the plain node name.

Tests: display-name unit cases (remark / empty / whitespace) and
view-level assertions for both audiences; the public contract
test's seeded expectation updated to the remark (its fixture sets
public_remark='shown publicly' on node 'PubNode').
