refactor(app-project): optimistic updates for YourProjectStats

[eatyourgreens]

• a new module-scoped bound function, mutate, in the useYourProjectStats module. mutate is generated each time that stats data is fetched from ERAS, and bound to the current cache key. It can be used to update the fetched stats.
• a new export from the useYourProjectStats module. updateYourStats runs an optimistic update of your stats for the current cache key, incrementing both counts when you press Done or Done & Talk, without revalidating the SWR cache.

Please request review from @zooniverse/frontend team or an individual member of that team.

Package

• app-project

Linked Issue and/or Talk Post

• closes Your Stats makes an expensive GET request on every classification #6588.

How to Review

https://local.zooniverse.org:3000/projects/eatyourgreens/-project-testing-ground/classify/workflow/3599?env=staging

You should see your stats increment instantly after each classification, but the fetched stats aren't revalidated (there won't be any HTTP requests to eras.zooniverse.org.)

updateYourStats runs an optimistic update of your stats for the current cache key, incrementing both counts when you press Done or Done & Talk, without revalidating the SWR cache.

This is a very jargon-laden way of saying it adds 1 to each of your total stats counts.

[eatyourgreens]

Does anyone know what mutate evaluates to here when the key is null? The old stats code kept a running count of classifications in the current tab, if you weren’t logged in. Just so you’d have some visible feedback that your classification had been saved, after you pressed Done.
