refactor: use CWallet const shared pointers when possible

While const shared_ptr<X> gives us an immutable shared pointer to a mutable X (we can't set it to some other X later), shared_ptr<const X> gives us a shared pointer to an immutable X. Importantly, we can recast shared_ptr<X> into shared_ptr<const X>, but not the other way around. We do this for two reasons: because it makes the code safer to guarantee the wallet is not modified, and because it further dispells the misconception that const shared_ptr<X> gives immutability to X.
