fix: use noble-chiseled-extra to include ICU for SqlClient globalization

noble-chiseled strips ICU libraries. Microsoft.Data.SqlClient requires ICU for globalization support and throws System.NotSupportedException: Globalization Invariant Mode is not supported without it.

Switch to noble-chiseled-extra which includes ICU and tzdata while retaining the security benefits of the chiseled image (minimal attack surface, non-root user, read-only-friendly).
