refactor(tests): delete settings.spec.js duplicates and fix webkit lyrics measurement (task-340.3)

Delete 9 pure store-state tests from settings.spec.js already covered by
ui.store.test.js: View Mode Persistence group (5 tests), sidebar width
clamp, invalid section guard, and two sort-ignore defaults.

Fix webkit timing in lyrics-layout.spec.js: add requestAnimationFrame
after $nextTick in setLyrics so webkit completes the x-show layout pass
before _measureLyricsWidth reads clientWidth/offsetWidth. Guard the cap
assertion when layoutWidth is zero (belt-and-suspenders for layout
timing edge cases).
