Legal API - update logic for populating legalName field in business response

[argush3]

Update business response for GET /businesses/ such that the correct legal name is returned for SP/GPs. The logic to be used to return the correct legal name for firms can be referenced from entity-bn

Logic for legal name:

• Return businesses.legal name when business type is not a firm
• Return legal name the way entity-bn does when business is a firm

TODOs

• [ ] Update json function in business model to return correct legal name for SP/GPs when enable-legal-name-fix feature flag is on. Note that this feature flag should exist already. Ensure to incorporate upcoming changes to entity-bn firm name retrieval logic.
• [ ] Get business endpoint should return expected legalName for firms
• [ ] Add/update unit tests to verify legal name is being returned correctly
