Institution Creation Backend Validation

As part of the #6452 hotfix, it was identified that the backend validations for the institution creation are not fully aligned with the UI.

**Acceptance criteria**
- [ ] Review the UI validations and ensure the API DTOs are in sync with the UI.
- [ ] Review the different paths for:
- [ ] Institution create/updated by the ministry; and
- [ ] Institution create/updated by the institution; and
- [ ] Any other UI affected by a shared DTO (e.g., address validation).
- [ ] For DTOs that are potentially shared, for instance, address validation, ensure the dependent DTO-related UI is in sync with the validations.
- [ ] For instance, when applying a max length constraint to the shared [AddressDetailsAPIInDTO](https://github.com/bcgov/SIMS/blob/main/sources/packages/backend/apps/api/src/route-controllers/models/common.dto.ts#L39-L85), ensure student and location addresses are also taken into consideration.
