Improve setup experience when user connects a Safe

[apbendi]

As reported by a user:

I just connected with a smart contract wallet (Safe). I understand that "receive" and "setup" does not work because I need an EOA to sign.

This is likely correct—user's probably can't go through the setup process with a contract wallet like Safe—but we likely don't provide a good error message or explanation for them as to why. We should test this out to see what the experience is currently like and make improvements to it as warranted.

When the user says they connected the safe what method did they use? I was able to setup up a safe on Umbra using wallet connect.

Let's add something similar to the argent warning about compatibility issues.

"Argent": {
  "warning": "Warning: Argent Compatibility Issues",
  "warning-paragraph": "<p class=\"text-bold\"> Umbra is not compatible with Argent's standard security model. While you can still use Umbra with Argent, you are at risk of losing funds if you switch devices or have to rely on social recovery without first withdrawing any funds sent to you via Umbra. </p> <p> Umbra works by generating app-specific keys derived from your wallet's private key. Argent is unique in that its security does not rely on your private key. This is good in many ways. </p> <p>When using Umbra, however, you must be aware of the following:</p> <ol> <li> If you recover your Argent wallet onto a new device, the new wallet will have the same address but a different private key. Unless you have access to the old device, funds sent via Umbra that you have not withdrawn will become unrecoverable. </li> <br /> <li> As a result, when you get a new device, you should withdraw all funds first using your old device, then repeat the Umbra account setup and re-publish your keys. Soon, the app will attempt to detect when you need to do this to minimize the chance of lost funds, but for now you must do it manually. </li> <br /> <li> Unlike other applications, the security of funds received by Umbra is not protected by the standard Argent security model, and instead they are just protected by your private key. </li> </ol>",

Issue to keep in mind when adding functionality to open a modal when the connecting contract is a safe. safe-global/safe-smart-account#714
