fix(vtex): render userSegment options and give birthday its own icon

userSegment `Props` was a union of interfaces whose only discriminant
(`segment`) was `@hide true`. deco wraps every block config as
`{ allOf: [PropsRef], properties: { __resolveType } }`, so admins that treat
`allOf` as an intersection flatten the union — the hidden discriminant
collapses and only a stray field (`months`) renders, giving no way to pick a
segment. Flatten `Props` to a single object with a visible `segment` enum so it
renders as an options dropdown; the handler already reads `props.segment` /
`props.months`, so behavior is unchanged.

Also give the birthday matcher `@icon gift` (was `calendar-event`, identical to
the generic Date matcher) so it has its own identity in the picker.
