fix: use correct href for phishing page proceed anyway button

[mindofmar]

Description

This PR makes several small optimizations and bug fixes to the way we capture metrics and display URLs for our phishing page.

• Improves consistency: Metrics always uses hostname now. Previously, blockedUrl being set to details.initiator would add a https:// prefix to our metrics whereas hostname would be tracked without it.
• Bug fix: for c2 domain blocks, we previously would display the c2 itself on the phishing page and as the 'Proceed anyway' link. This PR changes it to use the actual domain that the request came from, in order to improve clarity for the user.
• Bug fix: Fixes: https://github.com/MetaMask/MetaMask-planning/issues/6038

Note

Corrects phishing warning flow to display/proceed to the correct URL while standardizing metrics to use hostname.

• Background phishing detection (app/scripts/background.js):
  • Use href as blockedUrl and derive blockedHostname safely (fallback to original hostname/href on parse errors).
  • Metrics: send url and referrer.url as blockedHostname for consistency.
  • C2-detected requests: override blockedUrl with details.initiator for display/proceed behavior.
  • Redirect params: set hostname to blockedHostname and href to blockedUrl for the phishing warning page.
