Dispose the appender when mapped appender validation fails

CreateAppender<T, TMap> created the low-level appender and passed it to the
DuckDBMappedAppender constructor. When the constructor threw (no mappings,
wrong column count, type mismatch), nothing disposed the appender, and its
native objects stayed alive until the finalizer ran.
