Get sequence settings (optionally filter by code)

Return all 13 public settings for the sequence along with the <strong>full</strong> assigned schedule (<code>id</code>, <code>name</code>, <code>timezone</code>, <code>isDefault</code>), all four <code>priorityDistribution</code> options with the active one flagged (<code>active: true</code>), and the associated <code>client</code> (or <code>null</code>).

Pass the optional <code>code</code> query parameter (1–13) to return just that single setting as a one-element array — useful when you only need to read one flag. See OpenAPI.md.
