### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Start by reproducing the issue on an iPhone using the Authenticator's first screen with TOTP codes, checking build 2025.8.0 (135) and the provided screenshot. Trace how website icons are selected for TOTP entries; done means different websites display their corresponding icons instead of the standard icon.
