feat: offer the area code block on Lookup's result card

A +33 1 lookup showed the offer only after two scrolls and Open full
detail. The card now reuses areaCodeBlock and blockAreaCodeWithUndo, so
the label, description and Undo match the number's screen. Checked on
the S22 by scripts/device_smoke.py (+33 1 offered and undone, +81 42 not
offered).

   report itself stays sent. One report rarely blocks a number for everyone,
   so you kept getting the calls unless you also tapped Block. A number you'd
   blocked already keeps its block exactly as it was.
+- Lookup's result card now offers to block the number's whole area code,
+  with Undo, the same way a number's own screen does. Before, you had to
+  scroll down and open the full detail to find it.
