Sync descriptions and issues, run workflows nightly

mirror.js now keeps repo descriptions in step with GitHub. A new
sync-issues workflow copies issues, PR conversations and comments onto
the mirrors with GitHub's numbering. Shared API helpers move to
gitea-mirrors.js. Every workflow now runs once a night, 1.5 hours apart.
