This pull request updates the challenge review context feature to allow creating a review context for any existing challenge, not just those in DRAFT or REGISTRATION phases. However, updating a review context is still restricted to challenges in DRAFT status or with an open registration phase. The changes also add comprehensive unit tests for these behaviors and clarify related error messages.

Access control and validation changes:

• Creating a challenge review context is now allowed for any existing challenge, removing the previous restriction to DRAFT or REGISTRATION phases. [1] [2]
• Updating a challenge review context remains restricted to challenges in DRAFT status or with an open registration phase, with the validation method and error messages updated for clarity. [1] [2] [3]

Testing improvements:

• Added comprehensive unit tests in challenge-review-context.service.spec.ts to verify the new and existing behaviors for creating and updating review contexts under different challenge statuses and phases.
