What is the interpretation of Allah's saying: "Indeed, prayer prohibits immorality and wrongdoing" (Quran 29:45), and what is meant by "immorality and wrongdoing"? Is immorality [specifically] adultery, and wrongdoing [specifically] alcohol?

Prayer forbids indecency and evil because it involves remembering Allah through words and actions. As a whole, it acts like a preacher that deters one from committing sins and brings about Allah's pleasure. This includes the intention and standing before Allah, which reminds one to obey His commands and abstain from His prohibitions. Allah has endowed it with a divine characteristic to abandon indecency and evil. Indecency refers to every sin deemed egregious by divine laws and human nature, while evil refers to everything denounced by divine law and other sources. The interpretation of indecency as adultery and evil as intoxicants is an example of interpreting a general term by some of its specifics, as they are not restricted to these two only.
