Refactor: Replace UiEvents with Action in WorkplaceScreen

Replaced `UiEvents.Insert` with `Action.Insert` when adding media in the `Workplace
Screen`. This change likely improves consistency by using a common action system instead of UI-specific events.

- Updated `mediaInsert` and the image picker result handler to use `Action.Insert` instead of `UiEvents.Insert`.
