[DankActions] enhancement

A few enhancement suggestions for the `Dank Actions` plugin:

1. Add support for mouse scroll up/down events.
2. Allow multiple right click commands, with labels, such that if there is more than one, a popup menu is shown.
4. Add an ipc call to allow triggering a widget refresh/redraw, re-running the display/visibility commands.

The issue names the Dank Actions plugin but no files, tests, or entry points; start by locating that plugin in the dms-plugins repository and reviewing its current action and event handling. Completion would require addressing all three requested enhancements: scroll events, labeled multiple right-click commands, and an IPC-triggered widget refresh or redraw.
