Fix executemany SQL_C_NUMERIC mismatch for Decimal values outside MONEY range (GH-609)

The executemany auto-detection path set paramCType=SQL_C_NUMERIC for
Decimal values outside the MONEY range, but the conversion loop converts
all Decimals to strings. The C extension then received strings where it
expected NumericData structs, raising RuntimeError. Fixed by overriding
SQL_C_NUMERIC to SQL_C_CHAR in the auto-detection path, matching the
existing GH-503 fix in the setinputsizes path.

Fixes #609
