TL;DR
Question on superpositions
With superpositions, the matrix based equations imply that there is a finite number of possible superpositions. Descriptions of how to reproduce the 2-slit experiment prescribe a maximum distance the slits can be apart and still reproduce the experiment.

is there a way to determine the minimum and maximum angles a superposition could have from the emitter?

This question does not make much sense to me. For a double slit experiment, you need the slits to be within the uncertainty in the direction of the beam. But, also, if the slits are far apart and you have a very large uncertainty in the direction of the beam, then you will effectively get two separate single slit patterns, some distance apart.

What defines the boundaries of the uncertainty?

There is no definite boundary, but the probability distribution will drop off very quickly for a tightly focused beam.

So there is a non-zero chance that a single photon could impact a detector 180 degrees behind the emitter?

That's not really relevant. If the emitter is a simple source, then photons will be detected in all directions. If the emitter produces a focused beam, then the probability of being detected outside a narrow strip on the first screen would be vanishingly small.
