feat: CCP-5725 - Event CSTAR Group recipient option

[mgtennant]

Description

• Based on the Events branch (CCP-4999_events-page)
• Add CSTAR Groups to Event recipient options
  • Uses your SSO JWT to call CSTAR and fetch your groups
  • Group IDs are saved to event_channel_setting table
  • Add CSTAR route that will fetch the emails of group members, however, the CSTAR API requires an SSO JWT and so this currently cannot be used at send time.
