Use Eip1193Provider instead of onboard for dispatch calls

[usame-algan]

Description

Transaction dispatch calls are tightly coupled with onboard even though they are low-level functions and only need a standard Eip1193Provider. They also handle chain switching in case the wallet is on a different chain than the safe. This will be tackled as part of #3743

The goal is to not rely on our custom useOnboard state anymore but instead either switch to a different wallet solution or start using pre-defined hooks that onboard provides.

Requirements

• All dispatch functions should expect a Eip1193Provider instead of an onboard object
• Extract the assertWalletChain calls to switch the chain higher up the call tree to the components calling the dispatch functions
