Phishing/Malware site blocking on Brave iOS can be bypassed with trailing dot in hostname

## Summary: Phishing/Malware site blocking feature on Brave iOS blocks navigation to the domains in [simple_malware.txt](https://github.com/brave/brave-ios/blob/821785db8fc71fd084a8a0b2600ff43ea7165ce9/Client/WebFilters/SafeBrowsing/Lists/simple_malware.txt). But that logic doesn't care existence of a trailing dot in the hostname, so http://3e1.cn/ in the list is correctly blocked but [http://3e1.cn./](http://3e1.cn./) is not blocked. Safe browsing in Brave for PC/Mac (Chromium based) can blocks both URLs, so Brave iOS should align with it. ## Products affected: * Brave iOS nightly build ## Steps To Reproduce: * Enable "Blocking Phishing and Malware" feature on Setting * Open [http://3e1.cn./](http://3e1.cn./) ## Supporting Material/References: * See attached demonstration movie file ## Impact User is taken to the prohibited malware/phishing site with bypassing Brave Shield protection.
