fix: update ITs to use consolidated init.sql, remove dead code

- All 7 ClickHouse integration tests now load init.sql via shared
  ClickHouseTestHelper instead of deleted V1-V11 migration files
- Remove unused useScope exports (setApp, setRoute, setExchange, clearScope)
- Remove unused CSS classes (monoCell, punchcardStack)
- Update ui/README.md DS version to v0.1.28
