Merge origin/main into #426 after #424/#425 landed

#425 was squash-merged, so #426's base content now lives in main under a
different SHA. Reconciled the three resulting conflicts:

- .github/workflows/test.yml: kept #426's superset test list (its unification
  suites plus test_element_style.py); main had only element_style from #425.
- CHANGELOG.md: kept #426's version, which promotes main's "Unreleased"
  section into the "3.2.0" release and is a verified superset of main's
  content (no lines dropped).
- test_sports_base_characterization.py: kept #426's side for all three blocks.
  Two are semantic, not cosmetic: #425 pinned the pre-fix behaviour
  (hockey/baseball events dropped -> *_returns_none), while #426 carries the
  actual fixes (2486bdb2, 2eea7a7f) and updated the tests to *_still_extracts.
  Taking main's side would fail against #426's fixed code. The third is the
  get_background_service import path, which is .core in #426 after the package
  split. Also refreshed a stale comment that still named the removed test.

#424's global_config plumbing merges in cleanly; verified the interlock end to
end on the merged tree (global_config target_fps -> SportsScrollDisplay 90.0).
435 tests pass across the affected suites; the lone failure
(test_get_system_status) is one of the four pre-existing on main.
