Subject: Annotate the History list with each revision's lifecycle

Each row in nodes#show's History section now carries terse badges
from the action log: created, published, and restored (rollback
re-promotion), with date and actor, rendered from entry metadata
alone. Backfilled entries wear the inferred marker, so
reconstructed provenance stays distinguishable from witnessed
history. A revision that was published and later restored shows
both badges chronologically -- its true biography.

Only create and publish entries carry page_id; trash, restore, and
destroy annotate the node's own log zoom instead of any single
revision, by design.
