Filter pets by fostered on staff pet view

[mononoken]

Description

On the staff pets view, /staff/pets, we cannot filter pets by if they are fosterable or fostered. Currently, they only show "adopted" and "unadopted".

These filters work with ransack, and they may benefit from being reworked from their current state.

I haven't fully thought through this. If you have suggestions, let's think about how this works and make a clearer idea of what these options should be and what their names on the UI should be.

The cases desired to show:

• Pets who can be adopted but are not
• Pets that are adopted
• Pets who can be fostered but are not
• Pets that are fostered

Acceptance criteria

• [ ] Filter pets by all of the cases described
