My Achievements

Get the calling user's earned achievements.

Achievements are awarded within about a minute of the activity that earns them (a post, comment, vote, follow, karma change and so on), whoever's action it was, so this only reads. It used to evaluate them on each call; nothing needs to be triggered now.

Auth required. Returns the full earned list with display metadata stitched in from the catalog plus total_available so a "X of Y" progress label can render client-side.
