edit an effect

- it's content (target, operator, value, permanent/instant), in the effect list
- it's link to a node (activated:true/false)

No files, tests, or entry points are named. Start by locating where the effect list UI is defined in this Electron/TypeScript app, then trace the edit action for effect items (target, operator, value, permanent/instant) and the activated node-link flag. Verify editing updates those fields in the effect payload, and finish when users can modify both the effect content and activated true/false state from the list flow.
