Fix api-tokens date display + quiet authIO no-token log (#120)

- api_tokens.ejs: created_on/last_used_on come back from Redis as strings
  (model-redis only coerces fields with an explicit `type`), so `new Date(ms)`
  yielded "Invalid date". Use `moment(ms, "x")` (the hosts.ejs/dns.ejs
  precedent) which parses a numeric string-or-number as a Unix-ms timestamp.
- api_tokens.ejs: `isExpired` is a class getter not serialized to the client
  JSON, so the "expired" badge never showed — compute expiry in the view via
  `Date.now() > Number(expires_at)`. Also guard the `last_used_on: 0` / falsy
  case (string "0" is truthy) so unset timestamps render "—" not "1970".
- middleware/auth.js: authIO did `checkToken(socket.handshake.auth.token || 0)`,
  so any socket connect without a token (login page, pre-login) did an
  `AuthToken.get(0)` lookup and logged a noisy `EntryNotFound` trace. Guard:
  reject the socket with a generic 401 when there's no token (behavior-
  preserving — unauth sockets were already rejected; just no Redis lookup / 404).
- dns_provider.js: drop a stray `console.log('currentDomains:', ...)` debug
  line in updateDomains() (unrelated, noticed while investigating).
