Call this once after restoring a token from local storage, to confirm the token is valid, which address it belongs to, and when it expires. expiresAt is computed from the idle window, not from the 7d absolute cap — do not read it as "guaranteed valid until this moment".
Send Authorization: Bearer <token>. The token is issued by POST /api/v1/auth/verify, and expires after 24h idle or 7d after issuance.
