feat: Refactor endpoint listing into blueprint

- Moved endpoint listing and searching routes (`list_endpoints`, `search_endpoints`) and helper function (`get_routes`) from `app.py` into a new blueprint at `routes/endpoints.py`.
- Added `/endpoints` URL prefix to the blueprint.
- Registered the new `endpoints_bp` blueprint in `app.py`.
- Removed the original endpoint route definitions and helper function from `app.py`.
- Updated `url_for` calls in relevant templates (`endpoints.html`, `base.html`) to reference the new blueprint endpoints (e.g., `endpoints.list_endpoints`).
- Updated `templates/changelog/changelog.html` to document this refactoring.
