test(ui): extend the small-phone overflow guard (about, intro, profile)

Adds about, intro and the profile screen (identity card + Save button) to
the 320x568 overflow guard across es/pt/ast. All pass — these screens
already fit small phones; the guard now protects them from regressions.
15 cases green.
