feat: add registerable actions to ProcessorTimeline and RouteFlow

Both components now accept `actions` (static) or `getActions` (dynamic
per-item) props. When provided, a "⋮" trigger appears on hover that
opens a Dropdown menu. Click propagation is stopped so action clicks
don't fire the row/node click handler.
