fix(OwnableValidator): bump checknsignatures to revert-4-fix

[highskore]

Summary

• Pins @rhinestone/checknsignatures to the revert-4-fix/checknsignatures branch so the next OwnableValidator redeploy bakes in the un-bugged checkNSignatures (strict required-signatures count + revert on malformed contract sigs).
• Required for fixing ERC-1271 contract-owner flows (clients with smart-contract owners hit failures on the current default OwnableValidator deployment).
• All 51 OwnableValidator unit + integration tests pass against the new lib.

Notes

• pnpm install also updated transitive sentinellist (e722c5cc → 4b03ebb5) and solady (0.1.14 → 0.1.26). The new sentinellist's popAll resets entries[SENTINEL] = SENTINEL instead of leaving it cleared, which means SentinelListLib.alreadyInitialized() returns true after popAll.
• This does not affect OwnableValidator's behavior — its isInitialized checks threshold[smartAccount] != 0, not list state. SocialRecovery and WebAuthnValidator follow the same pattern and are also unaffected.
• It does break OwnableExecutor whose isInitialized calls accountOwners[smartAccount].alreadyInitialized() directly (2 integration tests now fail). OwnableExecutor is not part of this redeploy; tracking the fix separately.

Test plan

• forge build — compiles
• forge test --mp "test/OwnableValidator/**/*.sol" — 51/51 pass
• Run targeted redeploy of OwnableValidator from this branch
• Verify on-chain checkNSignatures reverts on malformed contract-sig payload

Pins @rhinestone/checknsignatures to the revert-4-fix/checknsignatures branch so the next OwnableValidator redeploy picks up the strict signature-count and malformed-contract-signature fixes.

Risk: High — this dependency update also lands a known transitive regression outside OwnableValidator on main.

This pin is also what pulls in the newer @rhinestone/sentinellist, and the PR notes say that version breaks OwnableExecutor because popAll() now leaves the list looking initialized. Since this merges to main, we would be landing a known regression outside OwnableValidator just to prep the redeploy. Please either pin/override the old sentinellist here or vendor the checkNSignatures fix so the repo stays green.
