/**
 * Shared date parsing utility that supports both Japanese era formats and Western calendar formats
 *
 * Note: Uses non-strict parsing for Western calendar formats, allowing flexible delimiters.
 * For example, both "2025-12-24" and "2025/12/24" are valid for format "YYYY-MM-DD".
 *
 * Also supports formats without delimiters as fallbacks because dayjs does not support them natively:
 * - YYYYMMDD format (8-digit number): "20251215" can be parsed even when format is "YYYY-MM-DD"
 * - YYYYMM format (6-digit number): "202512" can be parsed even when format is "YYYY-MM"
 *
 * @param inputString - The input string to parse
 *
 * @param format - The dayjs format to use for Western calendar parsing
 *
 * @returns Object with isValid flag and parsed Date result
