CND-94 pt 2 - Feature flag modernized deduplication

[mpeels]

Notes

1. Adds a feature flag to the PatientMatchingService to support modernized patient matching.
   a. Feature flag defaults to false so existing patient match logic will be used.
   b. If the flag is set to true, then an API call will be made to the deduplication service to perform a patient match check.
2. Resolves a whole host of sonar findings within PatientMatchingService.
3. Adds additional test coverage
