Add support for Testcontainers JDBC URLs

Enhanced JdbcUtil to automatically infer dialectName and driverClassName
from Testcontainers JDBC URLs (jdbc:tc:database_type:...).

This allows users to use Testcontainers URLs without manually specifying
the dialect and driver class, improving the developer experience when
working with integration tests.
