Three related fixes for IDL event processing:
1. idl.go: include EventType in dedup key so Deassert events are no
longer silently dropped as duplicates of their Assert counterparts.
2. gpu_status.go: treat Deassert events as clearing all GPU faults —
previously the code re-applied the same faulty GPU set from the
description, leaving GPUs stuck in Critical even after alarm cleared.
3. reanimator_models/converter: add bmc_event_summary section to the
Reanimator export — a deduplicated Critical/Warning event table with
Active/Resolved status derived from Assert/Deassert pairs.
