feat(auth): external sign-in for the website and admin panel

Players sign in to the website, and admins to the admin panel, with an
OpenID Connect provider (DorkNet:SignIn:*). The first sign-in links the
provider identity (issuer + subject) to a DorkNet account with that
account's password; after that the provider sign-in is enough.

- Cookie sessions per host, keys persisted in the database so redeploys
  keep people signed in; unlink, deletion or a ban ends the session.
- Link attempts limited to 5 failures per 15 minutes per identity and
  per username.
- Admin panel: "Sign in with ..." exchanges the session for the usual
  admin tokens via GET /api/admin/v1/sso (IsAdmin still required).
- Downloads: optional DorkNet:Downloads:RequireSignIn serves the
  manifest and files only to signed-in players; the Downloads and Quest
  pages offer sign-in instead.
- Website: sign-in in the header, /link and /account pages.

The game client's login is unchanged.
