The theme live-reload mechanism was already working correctly — the
previous QA failures were caused by flawed test methodology (modifying
files on disk while the editor had them open, so Cmd+S overwrote with
stale content). Added unit and Playwright tests that verify ALL theme
properties (including bullet-size/color) update when editing the raw
editor buffer and saving. Removed old skipped test file.
