fix(migrations): scope check constraint must accept UPPERCASE values

JPA persists enum DataScope as @Enumerated(EnumType.STRING) by default,
which writes the enum name verbatim — UPPERCASE. The original CHECK
constraint allowed only lowercase ('public','internal','restricted'),
making every insert violate it.

Drop and recreate constraint with UPPERCASE values to match enum names.
Applies to dictionary_definitions.scope and dictionary_records.data_scope.
