Add TaskQueue to interactables

[Ernest314]

There's currently a chance for updates from component interactions and interactable cleanup (and update, in the case of Selection) to cause a race condition. Putting all that logic in a TaskQueue would prevent this.

• [x] Pages
• [x] Selector
• [x] Confirm
• [x] Modal

Don't forget about Farm.Selection!

Turns out Confirm does need a TaskQueue, because the ephemeral message can still be sent to multiple devices if the same person has the channel open on multiple instances (e.g. devices) at once.

See #362 for Farm.Selection TaskQueue implementation.
