If they were playing transfers here, would it not be typical to treat 3H-3N as some kind of superacceptance?
Only typical for a certain type of player, and the evidence suggests this is not that type of player. In the clubs in which I play if the bidding went
1NT 2
♥[transfer]
2NT
responder would be totally confused, and would shrug her shoulders and bid 3NT with any type of strong hand, and pass with any type of weak hand.

Is the player allowed to "wake up" to the fact that they are not playing transfers by virtue of partner not alerting the 3H call? [Certainly she's allowed to wake up, but when partner's actions suggest that she wake up, I don't know that she can...]
No, the alert is unauthorised information, and she must make every effort possible not to gain from knowledge of the lack of alert.

It seems to me that 4S is an LA to 3N, and that the failure to alert is UI that demonstrably suggests passing 3N.
I think it suggests passing, yes. But whether 4
♠ is an LA is another matter.

Given that many tables played 4S-1, I think an adjustment (or at least a partial adjustment, if that's allowed in your jurisdiction) would be reasonable.
When you decide what to do in a ruling case, you ignore what happens at other tables.

But I'm just learning, so if this is nonsense, I'd be interested in hearing why (rather than just "LOL" or "NO"

)
Not nonsense, no, and I have tried to answer. It is a common failing on forums [fora?] to say something is wrong without explaining why and your reminder is good.
