 loader: preserve numeric DBF metadata in pgsql2shp

 Decode numeric typmod precision and scale when selecting DBF field
 metadata so pgsql2shp preserves fixed numeric declarations that fit in the
 DBF field-width limit. Keep legacy 32,10 metadata for untyped numeric
 values.

 Add pgsql2shp dumper coverage for portable numeric typmods, and gate
 PostgreSQL 15+ negative-scale numeric coverage behind the configured
 PostgreSQL version.

 Closes #2850
