Update reward info fetching and improve pool data handling

[trungbach]

This pull request includes several changes to the src/pages/Pools and src/reducer/onchainTokens.ts files to improve functionality and fix potential issues. The most important changes include updates to the reward information fetching logic, handling of null values, and enhancements to the token update process.

Improvements to reward information fetching:

• src/pages/Pools/hooks/hooks.ts: Modified the useQuery call in useGetRewardInfo to disable refetching on window focus, which can improve performance.

Handling of null values:

• src/pages/Pools/hooks/hooks.ts: Updated getClaimableInfoByPool to handle cases where pool.rewardPerSec might be null, preventing potential errors.

Enhancements to token update process:

• src/reducer/onchainTokens.ts: Added a call to addToOraichainTokens in optimisticUpdateToken to ensure tokens are properly added to the state.

Other changes:

• src/pages/Pools/index.tsx: Added useEffect import to manage side effects and updated ListPools and ListPoolsMobile components to display empty arrays when the address is not provided, improving conditional rendering logic. [1] [2]
• src/reducer/onchainTokens.ts: Imported updateAllOraichainTokens to ensure all tokens are updated correctly.
