Implement Plyr-based video player with comprehensive YouTube UI blocking

Rewrote VideoPlayerWithChapters component using plyr-react with best practices: - Use Plyr React component wrapper for proper integration - Aggressive YouTube UI hiding with correct parameters (controls=0, disablekb=1, fs=0) - Block right-click context menu globally - Block developer tools shortcuts (F12, Ctrl+Shift+I/J, Ctrl+U) - CSS pointer-events manipulation to block YouTube iframe interactions - Only Plyr controls remain interactive - Accurate time tracking via Plyr's timeupdate event - Chapter jump functionality via Plyr's currentTime API - Custom accent color support for Plyr controls - Hide YouTube's native play button with ::after overlay This implementation provides: ✅ Working timeline with accurate duration tracking ✅ Chapter navigation that jumps to correct timestamps ✅ Maximum prevention of YouTube UI access ✅ Custom Plyr controls with your accent color ✅ Right-click and dev tools blocking ✅ No "Watch on YouTube" or copy link buttons ✅ Clean user experience Based on recommended plyr-react implementation patterns. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
