[feature]: Add Toast messages for UI actions

Certain UI actions (like duplicating a project or workflow) happen without the user being notified they happened.
- Bigger problem when done inside the workflow view because the user has no way of seeing the duplication take effect
- Lesser problem when done inside the project view, but still lacking in UX

Will most likely include some global store that listens/tracks for actions that trigger a toast message to pop up
