Replace data/issues.json with content/_index.md files per issue

Issue metadata (title, description, season, status) now lives in
content/issues/XX/_index.md. terms.html reads from those pages via
$.Site.GetPage, driven by issueIds param in hugo.toml. Removes the
JSON data file and its generation from import-posts.py.
