Reset phishing warning triggers

Nobody has claimed this yet.

### What is this about?

I've clicked on "enter site anyway" on a phishing warning. Now I want the warning for that site to trigger again when I re-enter it. There seems to be no way to reset phishing warnings, nor edit the blocklist.

How can I do this?

### Scenario

- Enter deceptive site;
- Get the "phishing page" trigger;
- Continue to it anyway;
- Close or refresh page;
- Enter same deceptive site;
- Site enters directly, but I want the warning to trigger again.

A button such as "reset all phishing site warnings" should be a no-brainer. Alternatively, a way to edit the current blocklist, or to edit the current list of whitelisted domains, should exist.

No file, test, or entry point is named. Start by tracing the phishing-warning flow and the state used after choosing “enter site anyway”; define whether completion means a reset control, editable blocklist, or editable allowlist, then verify the reported scenario triggers the warning again.
