With the proper joinery should a frame survive a fall like this or
should it be expected to fail?

Should I be making the spline deeper or adding a key for additional
strength?

Judging from your description I would say that there was most likely a
combination of factors that caused the behavior.

That said, good glue, properly applied in the right temperature range, would
not have normally allowed the parts, particularly the splines in a miter
joint, to come apart as cleanly as you describe.

In addition, 1" splines probably didn't give you enough extra glue surface
area in a miter joint joining sides of that size.
