Get a schedule's editable configuration

Returns the full stored configuration of the schedule, in a format that you can edit with PATCH /schedules/ — targets, prompts, test users, headers, scope, timing, notifications, and uploads. Credentials are returned as metadata only (username, notes, MFA method, has_stored_secret) and headers as metadata only (name, notes, has_stored_value) — raw secrets such as passwords, TOTP seeds, header values, MFA inboxes, and login URLs are never included. Keep a stored header value on PATCH by sending keep_stored_value: true.
