fix(01): revise plans based on checker feedback

- Remove AbstractClickHouseIT and application-test.yml from Plan 01-01,
  move to Plan 01-03 Task 1 (reduces 01-01 from 15 to 13 files)
- Change Plan 01-02 Task 1 tdd="true" to tdd="false" (compile-only verify)
- Add DiagramRepository and MetricsRepository flush key_links to Plan 01-02
- Update VALIDATION.md: INGST-06 TTL maps to HealthControllerIT#ttlConfigured*
  instead of non-existent ClickHouseTtlIT

 Purpose: Establishes the storage foundation that all ingestion endpoints and future search queries depend on. The WriteBuffer is the central throughput mechanism -- all data flows through it before reaching ClickHouse.
