[CRCR] Add failed-tests-detail input to callback action and ingest path

Add support for per-test failure details in the CRCR pipeline. The
callback action now accepts a `failed-tests-detail` JSON array input
containing test name, classname, message, and duration for each failed
test. The ingest path (crcrUtils.ts) extracts and persists it as
`failed_tests_json` in DynamoDB/ClickHouse.

Size caps applied at both layers: max 50 entries, message truncated
to 500 chars. This prevents unbounded growth in DynamoDB items while
giving backend maintainers enough detail to identify which tests broke.

Addresses #8545 (ingest path portion).
