Add custom Timestamp type that wraps time.Time for Kanboard's Unix timestamp format: UnmarshalJSON supports: - Unix timestamps as integers - Empty strings and "0" strings as zero time - Null values as zero time - Numeric strings (e.g., "1609459200") MarshalJSON returns: - 0 for zero time - Unix timestamp for non-zero time Includes comprehensive tests for round-trip marshaling and struct embedding scenarios. Closes: kanboard-api-25y
