Active Stack Action

### Context

Clicking on "Active stack" anywhere in the UI does not actually bring the user directly to the `Stack` page, it just brings them one layer closer (models => model, model => prediction, prediction => stacks)

Once https://github.com/developmentseed/ml-enabler/pull/43 lands, we will be able to programmatically jump directly to the Stacks page

### Actions

- [ ] From the modesl page - clicking on "Active Stacks" jumps directly to the prediction stack page if there is only 1 active stack in the model
- [ ] From the models page - clicking on "Active Stacks" jumps to the prediction list if there is > 1 active stack
- [ ] From the specific model page - clicking "Active Stacks" jumps directly to the Stacks component
