- Use singleton container pattern for PostgreSQL + OpenSearch testcontainers
(fixes container lifecycle issues with @TestInstance(PER_CLASS))
- Fix table name route_executions → executions in DetailControllerIT and
ExecutionControllerIT
- Serialize processor headers as JSON (ObjectMapper) instead of Map.toString()
for JSONB column compatibility
- Add nested mapping for processors field in OpenSearch index template
- Use .keyword sub-field for term queries on dynamically mapped text fields
- Add wildcard fallback queries for all text searches (substring matching)
- Isolate stats tests with unique route names to prevent data contamination
- Wait for OpenSearch indexing in SearchControllerIT with targeted Awaitility
- Reduce OpenSearch debounce to 100ms in test profile
