What is the ruling on masturbation in this case, and is the husband sinful if he does not have intercourse with his wife while she desires to conceive, and is wishing for death permissible under these circumstances? And is a wife's wearing makeup and trousers during the engagement considered deception?

Masturbation is forbidden and harmful, and is not permissible except out of necessity, which is not present here. The husband must fulfill his wife's rights, among the greatest of which are sexual intercourse and procreation. It is not permissible to prevent a wife from procreating without a legitimate reason. It is not permissible to wish for death, and if cohabitation becomes impossible, then separation before procreation is easier, and divorce may sometimes be a matter of benefit. The wife wearing makeup and trousers may not be for the purpose of deception, and this is not among the defects that necessitate annulment.
