Pull request overview

This PR optimizes rendering performance in two components by strategically applying memoization and pre-computing formatted values. The changes eliminate redundant computations during render cycles while maintaining the same functional behavior.

Changes:

• Pre-compute formatted values (fee cut, reward cut, reward calls) in the OrchestratorList data accessor to avoid repeated formatting on each Cell render
• Replace useMemo hooks within Cell render functions with pre-computed values from the data accessor
• Add useMemo to StakeTransactions component to avoid re-filtering unbonding locks on every render
