Give action log entries per-verb icons

A muted glyph before each sentence makes both log surfaces
scannable by verb: create, publish, move, trash, restore,
destroy, and the discard pair. Rollback publishes get their own
icon (history) distinct from ordinary promotion. Unknown verbs
fall back to a dashed circle.
