Add support for ISO 8601 basic format and bare hours in parseTimeString()

New formats supported:

1. ISO 8601 basic format (compact, no colons):

   • "1430" → 14:30
   • "143045" → 14:30:45
   • "143045.123" → 14:30:45.123

2. Bare hours (defaults to :00 minutes):

   • "7" → 7:00
   • "7 AM" → 7:00 AM
   • "23" → 23:00

The parser intelligently detects the format based on digit count and presence of colons, maintaining full backward compatibility with existing formats.
