* fix(storage): defer S3 bucket verification until first access
* test(storage): cover deferred S3 bucket verification
* fix(runtime): widen backend container healthcheck window
* fix(runtime): widen backend container healthcheck window
* fix(test): use ddl-auto=create to prevent cross-context table drops
Multiple @SpringBootTest classes with different @MockBean configs
cause separate Spring contexts sharing the same H2 in-memory database.
With create-drop, one context's shutdown drops tables needed by another,
causing "Table not found (this database is empty)" errors.
* fix(test): widen awaitIndexedDocument timeout to 15s
CI runners are resource-constrained and async search indexing may not
complete within the previous 5-second window, causing flaky failures.
- Add server/Dockerfile.dev for fast local builds (JRE-only, ~70MB)
- Modify staging target to build JAR locally before Docker image
- Update .dockerignore to allow target/ directory for Dockerfile.dev
- Build time reduced from 17+ minutes to ~4 seconds
- Reuses local Maven cache (~/.m2/repository) instead of downloading in Docker
