Add a reader for the action log at admin/logHEADmaster

NodeActionsController#index lists entries newest-first, filterable
by node_id or user_id -- the two zoom shapes the log was designed
around. Rendering goes through NodeActionsHelper.action_summary,
which builds one sentence per entry from metadata alone, so entries
referencing deleted users or nodes render from their snapshots;
live associations only upgrade names to links. Unknown verbs
degrade to a generic sentence rather than an error, since the log
outlives its vocabulary. The helper is the escaping boundary:
every metadata value passes through h() before assembly.

Actor names link to the log's own user zoom rather than the unused
users page -- inspecting a suspicious user's other actions is the
intended workflow. Publish entries with a translation_diff expose
a collapsed per-locale change table linking out to the revision
itself. Sentences live in en.yml/de.yml following the existing
widget-string convention. nodes#show links to its node's zoomed
log.
