There isn't much Argonian lore out there. ESO is already the biggest source of lore on them. That being said I am not aware of any connection between Argonians and dragons existing.

Dragonknights are related to the Akaviri and we know the Akaviri have mysterious ties to the dragons.

All connections between them boil down to both being considered "lizards".

Ok, I've read some of the lore and I am confused about these "Dragon powers"

unless changes have been made - some abilities describe pulling on your dragon blood

This obviously doesn't mean "Dragonborn" because that requires Blood & Soul of a Dragon - this is not my question

My question is where does the Dragonblood come from? Is it a metaphor for the power of Mundus? Is it just fancy alteration?

The answer to this question is probably part of the mystery about how Akavir and the Dragons are connected. Akavir is the "land of dragons" in the Elven language and the Akaviri are certainly knowledgable about killing dragons. With Dragonknights following an Akaviri tradition, their powers share these ties to the Dragons, whatever those ties may be.

Sometimes it's frustrating that there are mysteries about this universe that the people living in said universe already know the answer to, but never tell nonetheless. We players have never seen someone from Akavir (without their armor on) and yet with the recent Akaviri invasion and the Akaviri potentates, every person in the pact and almost every person on Tamriel should know what they look like. Frustrating!

I always read it from the perspective of the lorebook written by Gabrielle. https://en.m.uesp.net/wiki/Online:Ardent_Flame:_Draconic_or_Endemic?

In essence Dragonknights are using already discovered magic but cast in a way to appear to be something else. This "Dragonblood" is a restoration spell that causes the blood to coagulate rapidly and form scabs over wounds. It is super fast and instant which would wow people and be seen as unnatural dragon power to the uneducated.

Basically it's an Akaviri martial arts fighting style meant to mimic the dragon themselves. They wanted to breath fire so they channeled the spell through their mouth instead of their hands, but they don't know the Thu'um that is truly Dragon magic. It's all pretend which is why I tell people Dragonknights use destruction, restoration, and alteration magic. That's all it is when you break it down and map it all out.

This!

You have to bear in mind that the schools of magic, for proper study of magecraft, haven't been invented yet. The mages guild, organization that began to teach magic to the comonfolk, is still in its infancy.

I'd assume dragonknights are hedge mages from the 2nd era, and when magic became more common and studied, such practices fell out of use.
