Recommend STRICT_ALL_TABLES for every install, not just development installs

Summary:
See D8308. Enabling STRICT_ALL_TABLES prevents this entire class of error, by fataling on truncation instead of truncating. We never want truncation; it is always bad and sometimes extremely bad.

We've recommended this mode for developer installs for a long time, and some users run with it enabled, so it's very unlikely to cause any issues (I've had it enabled locally for at least 6-8 months, I think).

Test Plan…
