## **Description**

Fixes two problems with Snaps usage of `PhishingController`. Following
#25839 the
PhishingController expects full URLs instead of hostnames as the input
to `testOrigin`. In that PR, the argument of `isOnPhishingList` was
incorrectly changed. This PR also patches in some changes from the
`snaps` repo that are currently blocked by a release:
MetaMask/snaps#2835,
MetaMask/snaps#2750

## **Manual testing steps**

1. Create a Snap that links to an URL blocked with `eth-phishing-detect`
2. See that triggering the Snap is disallowed if the user has phishing
detection enabled
