Enhancements in governance.ts for Improved Code Quality

This PR introduces several improvements to the governance.ts module to enhance readability, maintainability, and performance. Key changes include:

1. Code Deduplication:
   Refactored opsResolution and treasuryResolution to use a shared helper function resolutionHelper, reducing code duplication and improving maintainability.
2. Early Error Handling:
   Modified timelockDelaySet to check delay constraints at the beginning of the function. This change ensures that the function fails fast before performing any operations if the delay exceeds the allowed maximum.
3. Consistency in Async Operations:
   Updated asynchronous operations to consistently use async/await syntax, ensuring that all asynchronous code is easy to read and error handling is straightforward.

These changes aim to streamline the codebase and improve the overall quality of the governance module.
