Makes camera config dep. lazy.

This was needed because of a Dagger-related crash when querying the
content provider while a secondary user is selected. I don't understand
why it was happening, but this fixes it and is a safe fix.

Also formats the file using `ktfmt`.

Bug: 254333599
Test: when signed in with a secondary user and querying the quick
affordance content provider from the wallpaper picker experience, we no
longer see a crash.
