You could say the vestage is a lesser aedra considering you absorb aetherial power every time you use a skyshard

My question is this: are there "lesser aedra", and if so, why do we never see them as summonables of conjuration magic in any Elder Scrolls game?

All mortals are "lesser Aedra", in a sense. Aedra literally means "our ancestors".

Yes. In elvish.
So... want some "lesser aedra"? Go look at your nearest elf!
Or most other mortals, really... (though with some races, the daedra had a hand in their coming into being as well, not through creation, but through corruptiopn - orsimer, dunmer; and one may even be descendant from an entirely different force - the argonians are said to be childrena of the hist, which may be brought into being by interference from Sithis...)

Lore-wise... well, there are many tales told about it, but most overlap in that both sides have one common origin through the twin forces of of Anu (the force of order, light and creation) and Padomay (the force of chaos, darkness and entropy), once upon the dawn of time or shortly before that... giving birth fo the "first spirits", the Et'ada...

...then one side spent their power to create the mundus, the mortal realm (possibly through being tricked into doing so by Lorkhan, possibly just by happenstance). That is why they are considered "our ancestors" by the elves, since they are basically responsible for creation of everything, and gained the designation of "aedra". (the elves just think they were the first and best creation, but that's an elf arrogance thing, and they try very hard not to look at the dragons place in the history of nirn...)

...some of these "first spirits" also split off and fled to aetherius rather then spend all their energy creating the mundus, those were Magnus and his fellows, and they are generally associated with the birth of the sun and the stars... but are not active in Mundus per se... (though they are often associated with magic, so... in a way, they are...)

...and then there were the ones who did not throw in with the creation of the mundus at all, thus were called "daedra" (aka, "not our ancestors") but got jealous of it nonetheless (its why they mess with the mortal realm so much, methinks), and have been creating smaller stuff for themselves, daedra and oblivion planes, just to show the aedra they too can make nifty stuff, but it usually ends up just some cheap knockoff, since very little of oblivion is truly original work, mostly being a... skewed depiction of the mundus.

And then there are a few other powers, like Y'ffre for example, who are otherwise related (sort-of-demigod descendants/servants/creations of the aedra, if one follows the et'ada line of thinking) to those groups. And some mortals who are said to have ascended to demigod status, like Rahjin or the Wilderking (Wilderqueen)...

A really neat depiction of the TES pantheon would be:

(many thinkings to @Gidorick for making that one, its nifty!)

As for good and bad daedra... like most everything else, the divine and deadric powers in ESO also come in shades of grey instead of clearly defined "good-neutral-evil" alignments, though some shades are of course darker then others.
