feat(profile): public profile data for a ticket from Auth

GET /api/public/profiles/library with X-Profile-Ticket returns totals, status
counts, playing and finished games with rating; never notes, priority or the
Steam ID. Login filters reject the ticket, and Core keeps no copy of the
privacy flag.

+- `GET /api/public/profiles/library` with header `X-Profile-Ticket` (issued by Auth for a public profile, valid 10 minutes, see the Auth readme) returns totals, status counts, up to 8 playing and 12 finished games with rating. Never notes, priority or the Steam ID. Core keeps no copy of the privacy flag; the ticket is the proof.
