Add missing say test cases from canonical data (#855)

The say test suite was missing four cases that exist in the
problem-specifications canonical data: "thirty" (30), "ninety-nine" (99),
"two hundred" (200) and "nine hundred ninety-nine" (999).

Add the four cases to SayTest.scala (marked pending, matching the
existing convention) and sync their UUIDs into .meta/tests.toml.

The reference solution in .meta/Example.scala already handles all four;
verified all 19 tests pass via bin/test.
