fix: Respect survey label rules for WhatsApp CSAT template (#13285)

Ensure CSAT survey label rules are evaluated once in CsatSurveyService
before any channel-specific sending (including WhatsApp/Twilio
templates), remove the duplicated rule check from the template builder,
and cover the blocking-label scenario in service specs while simplifying
the template specs accordingly.
