The term seen more often is "maaseh kederah", which the gemara seems to
use interchangeably with "daysa".  In Yiddish it's "kashe".

The SAHarav gives this as *the* reason; he doesn't even bother citing
the other two reasons you cite.   The new annotated edition references
this to Hagahot haSMaK ch 222 (p 231), Mordechai remez 588, TaZ 453:1,
and Chok Yaacov 453:5.

The Taz in that location quotes the SMaK, but he says "issa" rather
than "daysa"; maybe it's a typo, or maybe the compilers of the new
edition misread it, or maybe by "issa" he doesn't mean dough but
"maaseh kedera".  One could resolve this by looking at the SMaK, but
I haven't got one to look at.

The Chok Yaacov does indeed bring "maaseh kedera" as the primary
reason, and then adds two more reasons, that kitniyos are sometimes
used to make bread and that sometimes grain is found in them.

IMHO part of the problem we English-speakers have in discussing
this is that English doesn't really have a word for daysa/maaseh-
kedera/kashe.   "Porridge" doesn't really cut it.  Porridge, at
least as it's used today, is breakfast, not dinner; it's oatmeal
or semolina, not cooked rice, wheat berries, couscous, barley,
buckwheat, millet, peas, lentils, etc.  *All* of those are "kashe"
in Yiddish, and "daysa" or "maaseh kedera" in Aramaic/Hebrew.
Without a single word to cover all of these things, we don't tend
to think of them as different flavours of the same food, and
therefore tend not to get how easy it would be to confuse them.
