 * Returns the theme settings for the given theme OID or theme settings, along with a non-fatal
 * error if loading a theme by OID failed.
 *
 * If the given theme is a theme OID, the theme settings will be fetched from the Sisense instance.
 * If the given theme is a theme settings object, the theme settings will be merged with parent's one and
 * returned as is.
 *
 * The returned theme settings are always usable: when loading by OID fails they fall back to the
 * inherited theme settings (the parent provider's, or the default ones at the root), and the failure
 * is surfaced through `error` for the caller to report.
 *
 * @param userTheme Theme OID or theme settings object
 * @returns The effective theme settings, and the theme loading error if one occurred
