hmm can we not have this being handled by DebugApi itself?

Have moved this part of logic to inside DebugApi

hmm unclear why this is needed. I know that those bounds are sometimes problematic but we need to figure out solutions for this that don't break such user-facing APIs

This targets on issue #20123 , as below :
Add a shared BadBlockStore (bounded, deduped, newest-first) and wire it into DebugApi
Implement debug_getBadBlocks to expose recent invalid blocks with full transactions, hash, and RLP
Listen for ConsensusEngineEvent::InvalidBlock, recover the sealed block with senders, and cache it for the debug API
