fix: make transaction list open by default and fix loading

- Change showTransactions initial state to true (open by default)
- Add proper wallet connection checks to useEffect
- Ensure transactions load when wallet is connected and supports list_transactions
- Add all necessary dependencies to useEffect for reliable loading
- Transactions now load automatically when wallet viewer opens
