dsOMOP 2.0.1

Patch release: disclosure-control hardening. Server counterpart of dsOMOPClient 2.1.0.

Security / disclosure

• omopValueCountsDS no longer accepts a client-settable suppress_small flag — small-count suppression is always enforced (a client could previously disable it).
• Drop raw MIN()/MAX() of person-level values from 8 aggregate query templates (extreme-value disclosure), keeping mean/sd/counts — consistent with the Achilles distribution policy.

Adds regression guards in test-disclosure.R.
