Xingbo Wang 214869aacd Persist fault injection logs and fail fast on expected-state trace writes (#14651) ...

Summary:
- switch fault injection error recording from an in-memory ring buffer to per-run fixed-record binary logs under `TEST_TMPDIR/fault_injection_logs` (or `/tmp/fault_injection_logs`) so crash paths survive DB reopen cleanup
- keep the raw and decoded fault logs for external artifact collection/cleanup, and make `db_crashtest` print consistent blackbox/whitebox summaries after decoding
- make expected-state tracing fail fast on trace write failures and document offline trace inspection via `trace_analyzer`
- add coverage for binary log persistence/decoding/truncated-tail handling and keep info logs excluded from fault injection
