meteor3: re-enable fixtures and sitemaps with async/Meteor-3 implementations

fixtures: drop @cleverbeagle/seeder (sync Mongo, unmaintained) for a small
idempotent async seeder (same dev accounts). sitemaps: drop dead
gadicohen:sitemaps for a WebApp.connectHandlers /sitemap.xml with the same
static page list (the per-fire section was already disabled). Verified on
dev boot: 6 users ensured, sitemap serving; REST smoke byte-identical.
