Featured Pets: improvements

[kasugaijin]

On the org home page, we see some feature pets. Let's improve this:

• this section should render conditionally, and only show if the collection of pets passed to the view is not empty
• if you look at the controller, the @pets collection query should be improved. The collection is set using a sample of 4, but this fails when the available pets is less than 4, because it starts to duplicate. So, I think we need a check there to see if the total number of adoptable pets is greater than 4, then sample 4, otherwise, return all pets (could be 1, 2, or 3 in total). Note, we do not need this line in the query .where(organization: Current.organization) because all Pet queries in this controller scope are already scoped to the tenant. Finally please use the Pet.unadopted scope to only return adoptable pets.
• try uploading images of different sizes and you will see the cards end up being slightly different heights based on the uploaded image, so please enforce a consistent height for all images that display in the cards

Example of different height images, that should be the same height
