test(sqlx): add ORE equality/inequality variant tests

- Add ORE64 equality and inequality tests
- Add CLLW_U64_8 variant tests (equality, inequality, <=)
- Add CLLW_VAR_8 variant tests (equality, inequality, <=)
- Tests multiple ORE encryption schemes
- Migrated from src/operators/*_ore*.sql (39 assertions total)
  - =_ore_test.sql, <>_ore_test.sql
  - =_ore_cllw_u64_8_test.sql, <>_ore_cllw_u64_8_test.sql
  - =_ore_cllw_var_8_test.sql, <>_ore_cllw_var_8_test.sql
  - <=_ore_cllw_u64_8_test.sql, <=_ore_cllw_var_8_test.sql
- Coverage: 208/513 (40.5%)
