Start server at onInitWallet and add wallet password handler

- Add onInitWallet to HttpApiMain and start http server there
- Add onRequestWalletPassword to BisqSetupListener
- Override setupHandlers in HttpApiHeadlessApp and adjust
setRequestWalletPasswordHandler (impl. missing)
- Add onRequestWalletPassword to HttpApiMain
