TutorialVault: complete Tauri v2 port with runtime fixes

Browse Source 
Rename from TutorialDock to TutorialVault. Remove legacy Python app
and scripts. Fix video playback, subtitles, metadata display, window
state persistence, and auto-download of ffmpeg/ffprobe on first run.
Bundle fonts via npm instead of runtime download.
