feat(backend): implement brain-prompt link (#831)

* feat: add prompt_id field to brain

* feat(Prompt controller): update prompt routes

* feat: remove unused private prompts

* refactor: add BrainEntity and repo and service

* tests: partially type main Repository

* feat: add PromptStatusEnum enum

* feat: change delete prompt repository return type
