Support DD/MM/YYYY WHOIS date parsing

Add handling for European-style dates (DD/MM/YYYY and DD/MM/YYYY HH:MM:SS) before calling strtotime. The code detects a leading DD/MM/YYYY pattern, interprets it as day/month/year when day>12 or when both day and month are <=12 (favoring European format used by many WHOIS servers like .pt, .es, .fr), then converts it to YYYY-MM-DD with any time part preserved. If month>12 the original string is left for strtotime to handle. This improves robust parsing of WHOIS date strings from servers that use day-first formats.
