[Aerilym]

This pull request introduces optimizations and enhancements to the apps/staking modules and components, primarily focusing on improving performance with memoization and ensuring consistent precision in formatting token balances. The most important changes are grouped below by theme.

Performance Optimizations:

• Updated the useVestingEndTime hook to use useMemo for computing the date and unit values, reducing unnecessary recalculations.

Token Balance Precision:

• Introduced the SENT_DECIMALS constant in multiple components and updated the formatSENTBigInt calls to include it, ensuring token balances are formatted with consistent precision:
  • VestingUnstakedBalanceModule.tsx now includes formattedAmountAccurate for higher precision.
  • VestingHandler.tsx uses SENT_DECIMALS for formatting contract.initial_amount.
  • VestingInfo.tsx applies SENT_DECIMALS for initial_amount and updates the unstaked balance to use formattedAmountAccurate. [1] [2]… days
