refactor: replace math test with practical badge count test

Changed test from artificial computation ((17*2)+3=37) to real-world
functionality testing: counting third-party domains shown in badge.

Test flow:
1. Visit news.ycombinator.com → verify badge = 0 (no trackers)
2. Visit pudelek.pl → verify badge > 0 (has trackers)

Changes:
- background.ts: handler returns badgeCount from getClustersForOrigin()
- test-content-script.js: sends origin, stores badgeCount in DOM
- test-lib.js: testBadgeCount() replaces testBackgroundComputation()
- test_verify.py: tests two real sites instead of math computation

This tests actual Rentgen functionality: third-party domain detection.
