Limit vault blob broadcast concurrency

[prashantkumar1982]

Summary

• Limits Vault observation blob broadcasts to at most 10 in-flight calls so large pending queues do not create unbounded goroutine fan-out during an OCR round.
• Keeps the existing per-blob timeout and graceful skip behavior for individual broadcast or marshal failures.
• Adds a focused regression test that holds broadcasts open and asserts concurrency never exceeds the configured limit.
