Pull request overview

This PR refactors the swap functionality by consolidating and modernizing the swap-related hooks and components. The changes centralize swap logic into a new hooks/swap module, remove outdated swap implementations from the stake actions, and update dependencies to support the new swap architecture.

Changes:

• Consolidated swap hooks into a centralized hooks/swap module with improved SDK integration
• Removed redundant swap-related code from stake actions and replaced with centralized swap hooks
• Updated transaction flow to eliminate the SetNextTransactionsFailed callback in favor of a simpler setTransaction API
• Added new store slices for vault validators, user roles, and allocator actions
