Add permit flashtestations tx calls from builder

[avalonche]

📝 Summary

Add permit function calls so that tee signer don't need funding to do the flashtestation transactions. Adds additional flashtestation tests and improves error handling.

CLI Changes

--flashtestations.use-permit enables the permit contract call and does not attempt to fund the tee key. It would use the builder key and many flags such as --flashtestations.rpc-url, --flashtestations.funding-key will not be needed to support flashtestations

---

✅ I have completed the following steps:

• Run make lint
• Run make test
• Added tests (if applicable)

it starts to look scary :)

we can move Extra fields to ExtraCtx :)

Pull Request Overview

Adds permit-based registration and block proof verification for flashtestations so the TEE signer no longer needs funding; introduces new tests and refactors builder transaction simulation to support permit flows.

• Introduces EIP-712 style permit functions on registry and builder policy contracts plus related signature/nonce logic.
• Refactors builder transaction trait and implementations to generic over extra context and execution info, adding unified simulation helpers and error types.
• Adds CLI flag --flashtestations.use-permit and corresponding test coverage for permit registration and block proof flows.
