fix: rename bug card anchor to div with _card_link include and add admin role tests

The bug list template wraps each bug in a `<div class="bug-card card-link-host">` instead of a bare `<a>`, pulling in `_card_link.html` for proper link semantics. Two new integration tests (`test_bug_detail_renders_for_member` and `test_bug_detail_renders_for_admin`) verify that the `/bugs/{number}` endpoint returns 200 for both roles, that the "Close ticket" button is absent for members and present for admins, and that the JSON response exposes `viewer_is_admin` as a boolean. Supporting helpers `_role_user` and `_open_ticket` create users with a specific role and open a Gitea-backed ticket.
