Standard Agent, Role, Role target (#16499)

# Introduction
In this pullrequest have been migrated to the flat standard entities:
Role, Agent and RoleTargets.

## What happens
- Removed createStandardMorph tool util in favor of dynamic typing of
`createMorphOrRelationStandardField`
- Implemented a command to remove standard agents and their role that
has been removed in https://github.com/twentyhq/twenty/pull/16513 also
added a default role target to data manipulator role to the only
remaining agent
- Implemented an agent deleteMany service handler
