chore: remove IS_ROW_LEVEL_PERMISSION_PREDICATES_ENABLED and IS_DATE_TIME_WHOLE_DAY_FILTER_ENABLED feature flags (#19082)

## Summary
- Removes `IS_ROW_LEVEL_PERMISSION_PREDICATES_ENABLED` feature flag,
making row-level permission predicates always enabled. Removes
early-return guards from query builders (select, update, insert) and the
shared utility, the public feature flag metadata entry, and
`updateFeatureFlag` calls from integration tests.
- Removes `IS_DATE_TIME_WHOLE_DAY_FILTER_ENABLED` feature flag, making
whole-day datetime filtering always enabled. Simplifies filter input
components and hooks to always use date-only format for `IS` operand on
`DATE_TIME` fields.
- Cleans up enum definitions, seed data, generated schema files, and
test mocks for both flags.
