Fix/sequencer

[glitch003]

• Optimistic nonce calculation
• Auto retries with backoff if it fails
• Periodically refresh the nonce from chain or during failure
• Sequencer actually works

Pull Request Overview

This PR implements optimistic nonce management to prevent nonce collisions when handling concurrent requests, particularly for PKP minting and payee delegation operations. The changes replace the existing sequencer-based approach with a more efficient system that assigns unique nonces optimistically.

• Replaces the existing Sequencer-based transaction handling with a new OptimisticNonceManager
• Adds comprehensive load testing for concurrent transaction scenarios
• Modifies rate limiting to skip test API keys for testing purposes

lit.ts:1

• The function has removed all capacity token logic (lines that were checking for existing tokens, minting new ones, etc.) without explanation. This appears to be a significant behavioral change that should be documented or the removed logic should be preserved if still needed.

tests/routes/delegate/addPayee.test.ts:1

• The function generateAuthMethod is creating auth method data but this is inconsistent with the test context. This appears to be for PKP minting, not for adding payees. The function should generate unique payee addresses instead.

The background confirmation tracking with tx.wait() creates unhandled promise rejections if the transaction fails after the function returns. Consider using a more robust background task management approach or at least add .catch() to prevent unhandled rejections from propagating.
