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.

+        - Quote sent — sends the customer a link to review and approve or decline their quote.

         **Sending a quote approval link via SMS:**
         On any quote's Details page, click **Send Quote via SMS**. The system texts the customer's mobile number a short message with the approval link. If no valid approval token exists yet, one is generated automatically. If an email was already sent for the same quote, the existing token is reused so both the email link and the SMS link remain valid simultaneously. The customer follows the link to the self-service approval portal and can approve or decline from their phone. Prospects (non-customers) receive the SMS at their ProspectPhone number without requiring an opt-in check; registered customers must have SMS Opt-In enabled.
