Allow Challenge Authors to Create and View Writeups Without Solving the Challenge

[yulmwu]

Previously, even challenge authors had to solve their own challenge in order to create a writeup or view writeups written by other users.

This PR changes the behavior so that challenge authors can create and view writeups regardless of whether they have solved the challenge.

Pull request overview

Enables challenge creators (authors) to create writeups and view writeup contents for their own challenges even if they haven’t solved the challenge, aligning backend authorization, frontend gating, documentation, and tests with the new rule.

Changes:

• Backend: centralize writeup-content access checks to allow challenge creators OR solvers to view/create writeups.
• Tests: add service-level and HTTP integration coverage for creator access and repo failure paths.
• Frontend/docs: update UI gating for writeup creation and document the new can_view_content semantics.
