SWAP UX IMPROVEMENT

### Feature description

1. Show available token balance directly on the swap interface, so users know how much they have before entering an amount. Because sometimes, i want to carry out a swap and i would have forgotten the amount i have in the wallet, so i always have to go back to the main page. It's stressful dude.

2. Add a percentage selector (e.g. 25%, 50%, 75%, 100%) around the blue-marked area, allowing users to quickly choose how much of their balance they want to swap.

3. I think we should also be able to bridge inside the wallet (on mainnet of course)

### Why is this feature needed?

ADDITIONAL INFORMATION ON THE SWAP SIDE UX CAN POTENTIALLY IMPROVE USERS EXPERIENCE

Analise os componentes da interface de troca no código frontend da carteira, provavelmente em src/components ou src/views. Encontre onde os saldos de tokens são buscados e exibidos. O seletor de porcentagem seria adicionado perto do campo de entrada de valor. Verifique os padrões de UI existentes para exibição de saldo e grupos de botões. Os testes envolvem verificar se o saldo é atualizado corretamente e se os cálculos de porcentagem funcionam.
