What: extends three leaf modules to their final NLE-stack form, tests in the same change: timelineInspector (isAudioTimelineElement, resolveBeatSourceTrack), timelineZoom (zoom/pps math incl. computePinnedZoomPercent), and studioUiPreferences (persisted editor prefs). Why: leaf dependencies of the NLE timeline stack; landing them first keeps the later glue PRs to wiring. How: additive from the consumer side — every export main already uses is unchanged (typecheck against main's consumers passes untouched); every new export is exercised by a test in this PR. Test plan: bunx vitest run on the three test files; tsc --noEmit in packages/studio; fallow audit --base origin/main clean.
