[Bug]: Support dotbit(.bit) id/Unable to use dotbit(.bit) in MM

### Describe the bug

Description:
At the moment it appears you can only use ENS or Unstoppable Domains to send funds, if you don’t want to use the long address. Why not support more such projects like dotbit (www.did.id) etc, which do has some interesting features with added security and large user base

Purpose:
Support for sending funds using more popular DIDs with large user base will make life easier for the users and helps prevent sending funds to the wrong address when you copy and paste long addresses.

Extension/Mobile/Both:
Both

### Steps to reproduce

1)Opened MM
2)Click sent
3)Enter my dotbit id

### Error messages or log output

### Additional context

_No response_

The issue identifies the send flow and existing ENS and Unstoppable Domains support, but names no files or tests. Start by locating address-name resolution in the send flow and reviewing how those providers are integrated; done means dotbit IDs resolve reliably on extension and mobile, with coverage for supported and unsupported inputs.
