Also, why isn't Hogwarts warded somehow against Portkeys?

When Snape and McGonnagal travel to Mary's, they have to take the Floo to Gringotts first, and remark that this is the fastest way out of Hogwarts. Presumably a Portkey would be faster (since it could take them directly where they wished), so either Dumbledore doesn't have Portkeys prepped for major locations like Diagon Alley (which would be stupid), or MoR!Hogwarts is warded against leaving by portkey.

MoR!Hogwarts is warded against leaving by portkey.

Confirmed:

Harry stared down at the pack of cards.

It couldn't take him anywhere else, not right now, portkeys didn't work here.

The instructions also explicitly state that he has to take them beyond the edge of the Hogwarts wards for the cards work.

Also, Quirrell transported Harry using a coin-shaped portkey, and they had to leave the wards first.

Either that or Portkeys take some difficult preparation and have a limited lifetime in which they will work. Requiring a trip to the target location with a lifetime limit of as little as a day would not stomp over any of their uses in cannon or in MoR up to this point IIRC. This would of course preclude Dumbledore from having Portkeys on hand to go to Diagon Alley.

It would render the king of hearts portkey Harry got from Santa Claus useless.

Not if Santa Claus intends to stick around and either recharge the king of hearts or wait for Harry to trigger it, and then transport him manually, but that's pushing it way too far.
