Create Developer-Mode Setting (related to SIWE domain binding)

[digiwand]

Description

In order to protect users, we want to strictly enforce domain-binding logic for Sign-in With Ethereum (SIWE) while supporting the developers.

To do this, we'd like a developer-mode setting that will allow developers to disable the strict domain-binding check.

See details and discussion here:
#18188 (comment)

Prerequisite

Needs design

Spec

• Needs to be communicated to developers
• Clearly state developer-mode is unsafe
• Unlock developer-mode only in Flask or beta
  • Is there a way to redirect users from stable to Flask or beta if it may be applicable? ideas: note in settings, add in response when RPC requests are rejected due to domain binding.
• Unsafe developer mode unblocks domain bindings
  • To confirm, will this bypass warning modals as well?

---

Another consideration has been to apply a specific setting to disable the domain-binding check in Flask or beta. This could be a plan B.
