Update all existing actions to use the new placements.
Review Request #14715 — Created Nov. 28, 2025 and submitted — Latest diff uploaded
This updates all the built-in actions in the UI to set placements
instead of attachments and parent IDs. This brings them up to the modern
interface, and enables the actions to be used in other attachment points
as needed.
Unit tests pass.
Tested all these actions in the UI.
