Blip 2.0.4

Fixed

• blip-check probed a single, unordered Contacts source; a stale CardDAV
  .abcddb sorting first produced a false "contacts ❌ — grant Full Disk
  Access" during blip-setup even though contacts and avatars worked. It now
  probes every source like the contacts tool does and fails only when none
  opens. First outside contribution — @jethrojones (#2). Thank you.
