Answer 1

She does have nose ridges:

These look to be about the same as her nose when she last appeared, in "Preemptive Strike" (The Next Generation, S7E24; image from https://memory-alpha.fandom.com/wiki/Ro_Laren):

It has been about 30 years in real time and within the Star Trek chronology, but this is very much the same nose, with the same number of ridges. Different makeup, lighting and filming technology might have made the prosthesis less obvious than it was in TNG.

In her first appearances, she had extra ridges extending over her eyebrows, like other Bajorans. This was changed as an element of Bajoran makeup, for artistic reaons, but has never been explained in-universe. If there is an in-universe explanation, then whatever happened would have taken place during the course of the Enterprise-D's mission in The Next Generation, and not in the intervening years.
