feat: gate sounds/stickers/effects UI behind feature flags

FEATURES in src/features.ts (all false) hides the assets-panel tabs and
views, the clip effects properties tab, and the timeline effects badge.
Existing project data still renders and stays editable (standalone effect
tab, sticker config, renderer nodes untouched).
