Rework attributes from integrations

The attributes that come from integrations such as IQVIA or Veeva have been reworked to allow for better availability across different implementations within the Identity Platform and underlying services. The following benefits have already been implemented because of this rework on the type of integrations:

• Added the ability to search for exact Onekey ID or Veeva ID through global search bar
• Added the ability to specifically override these type of integration attributes if needed
• Added the ability to merge data from these type of integrations into Unify
