Matching metadata fix

[tcdahlberg]

Critical Changes

Changes

• Custom meta data contact matching mapping in concert with matching rules were not honoring the matching only flag and were copying matching only data into the created new contact (lead/person account). matching only fields are now removed from created object
• QR code in the formula for the field Registrant_Id_QR_Code__c was not rendering correctly in transactional email. This bug has been fixed

Issues Closed

• Closes [BUG] QR code not rendering in transactional emails #641
• Closes [BUG] - The Matching Only flag is not respected with the Summit Events Contact Matching Mappings within the Custom Metadata Types #640

Pull request overview

This pull request addresses two critical bugs in the Summit Events application:

1. Matching metadata fix: Custom metadata contact matching mappings were incorrectly copying "matching only" fields into newly created contacts, leads, and person accounts. The fix introduces a new removeMatchOnlyFields method that filters out these fields before record creation.

2. QR code rendering fix: QR code images in transactional emails were not rendering correctly. The fix refactors the email template processing to properly handle image encoding (using the _IM1_ to _IM5_ format) and improves link encoding handling.

Changes:

• Added removeMatchOnlyFields method to filter out matching-only fields before creating new Contact/Lead/Account records
• Updated SOQL query to include Matching_Only__c field in mapping retrieval
• Refactored email template processing to handle image encoding for QR codes
• Added comprehensive unit tests for the new removeMatchOnlyFields functionality
• Fixed typo in method name from savTask to saveTask
