fix(inspur): correctly handle PCIe Assert/Deassert GPU fault events

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.
