Enhanced MQ publishers to utilize the new logical types:
- Updated convertToRecordValue() to use TimestampValue instead of string RFC3339
- Added DateValue support for birth_date field (days since epoch)
- Added DecimalValue support for precise_amount field with configurable precision/scale
- Enhanced UserEvent struct with PreciseAmount and BirthDate fields
- Added convertToDecimal() helper using big.Rat for precise decimal conversion
- Updated test data generator to produce varied birth dates (1970-2005) and precise amounts
Publishers now generate structured data with proper logical types:
- ✅ TIMESTAMP: Microsecond precision UTC timestamps
- ✅ DATE: Birth dates as days since Unix epoch
- ✅ DECIMAL: Precise amounts with 18-digit precision, 4-decimal scale
Successfully tested with PostgreSQL integration - all topics created with logical type data.
