Even atheism is a system of belief. Believing in the absence of a deity is still a relationship with a deity.
Not necessarily. Do you consider yourself to have a relationship with every god you don't believe in? Atheism does not have to mean believing in the absence of a deity--that's only hard atheism. Soft atheism is the lack of belief in any deities.
I'm pretty open about people putting religion in their fics if they're doing it in a way that I buy within the fic and if it doesn't seem to contradict canon. I think if I heard about the Dursleys locking Harry in a cupboard while they went to church my first thought would be that it was an Americanism, simply because I'd assume the author pictured the Dursleys as the kind of people you've described, who lived in a place where church was expected. Where as in canon church is never mentioned, and I think it would have been there along with the garden club if it were that kind of a factor. (Particularly if Petunia was locking Harry up before going, or forcing him to be polite and seemingly grateful at the service--I can't imagine JKR missing the chance to point out the hypocrisy of their religious belief.)
For Wizards I often don't make much of a distinction. The books include a Fat Friar, and they celebrate Easter and Christmas. You'd have to convince me of a character having a specific history or belief system, but I wouldn't automatically not believe it just because the character was Pure-blood. (Remus is a Half-blood, btw, I think JKR has said, but I don't know exactly what his background is.)
Hogwarts doesn't have as much religious history as it might--a lot of old boarding schools one would expect to have a chapel, for instance, even if the kids weren't required to attend it once a week. But I wouldn't be thrown out if someone painted a convincing religious history for a Pure-blood family. I've always assumed Parvati had two Wizard parents since Pansy seemed to know her. I wouldn't have trouble with her being both Pure-blood and Hindu if it was convincing in the story.
