feat(admin): make suspicious domains configurable

[markijbema]

Summary

• Adds bookmarkable URLs for each Blacklisted Domains admin tab via ?tab=edit|stats|suspicious.
• Makes the Suspicious tab's high-volume provider noise filter configurable with a default-on checkbox.
• Keeps the existing 30% blocked-account threshold as the default server-side behavior while allowing admins to disable it.

Verification

• Not manually verified in browser.

Visual Changes

Reviewer Notes

• The Suspicious query still defaults to hiding high-volume providers when called without input.

Executive Summary

All three changed files are correct — the optional input schema with conditional .having() filter, the checkbox toggle with URL-based tab navigation, and the new test case are all sound with no security, runtime, or logic issues.
