feat(seekbar): configurable seekbar styles with animated preview
Add five seekbar styles selectable in Settings → Appearance: Waveform, Line & Dot, Bar, Thick Bar, and Segmented. Each option shows an animated canvas preview using requestAnimationFrame. Style is persisted in authStore (seekbarStyle, default: waveform). Translations added for all 7 languages. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
