Settle reward hooks before exhausted book rotation

[dangerousfood]

Summary

• finalize each enabled bid and ask hook before an exhausted book is rotated
• report the historical book's live top amount with an incoming nonce of zero, then disable its hook flags
• preserve the existing 200,000 gas cap and best-effort hook failure boundary
• cover both-side closure directly and extend the multi-pool invariant model across recording and reverting hook configurations
