[Bug]: HTTP protocol is shown as secure like HTTPS with a padlock mark in DApp on MetaMask Android

### Describe the bug

This vulnerability occurs when a MetaMask DApp on Android does not implement secure address bar design principles, causing HTTP to be displayed as secure andsimilar to HTTPS protocol with a padlock. On iOS, HTTP sites cannot be accessed, but on Android they can. Even worse, the HTTP protocol is shown with a padlock icon in the address bar, misleading users into thinking the connection is secure

### Expected behavior

MetaMask Android DApp should mark HTTP protocol sites as insecure with a warning symbol, or simply prevent the DApp from accessing HTTP sites.

### Steps to reproduce

Just simply access http://httpforever.com/ on MetaMask Android DApp and you'll see the address bar mark the HTTP protocol sites same as HTTPS, with a padlock icon mark.

### Error messages or log output

### Detection stage

In production (default)

### Version

### Build type

None

### Device

Samsung A56 with Latest OS Version

### Operating system

Android

### Additional context

Actually, I reported this vulnerability on HackerOne as a security issue. However, I’m not sure why the H1 analyst closed my report as informative. I would like the MetaMask team to take a closer look at this issue, as I believe it could be considered a high severity security problem. I’m also reporting it here on GitHub because, as a daily active MetaMask user, I want to see this issue fixed. But, if you have time, please review my report on HackerOne again :)

### Severity

_No response_

Reproduce the behavior by opening http://httpforever.com/ in the MetaMask Android DApp browser and compare its address-bar indicator with an HTTPS site. Trace the address-bar protocol handling and verify that HTTP is shown as insecure or blocked while HTTPS retains its secure indicator.
