fix(native): mail-pattern domain extraction + drop Pressable from FormSheet

Two bugs reported on the new mail-pattern flow:

1. The sheet sent the full local@domain.tld pattern to the backend so a
   user blocking communications@only4-subscribers.com would only catch
   that exact local-part — newsletter@, info@, promo@ from the same
   sender would slip through. Casino affiliates rotate the local-part
   on every blast while keeping the domain stable, so we now strip the
   local-part on submit. The preview-card under the input shows what
   actually gets stored (only4-subscribers.com), so the user sees the
   pattern that will hit. Bare tokens without "@" stay as-is and reach
   the backend as display-name candidates.

2. FormSheet's backdrop was a <Pressable> — straight violation of the
   "TouchableOpacity, never Pressable" rule. Swapped for
   <TouchableOpacity activeOpacity={1}> so the tap-to-dismiss still
   works with no visible feedback on the dim layer.
