Add Quote Sent SMS template and fix consent confirmation wording

Adds a customizable QuoteSent SMS template to seed data and
DefaultTemplates so companies can edit the quote approval message
from Notification Templates. Wires NotifyQuoteSentSmsAsync to use
the template system instead of a hardcoded string. Updates
SmsConsentConfirmation wording to mention quote approvals alongside
job updates. Help docs and AI knowledge base updated to match.
