MAESTRO: Fix keyboard-shortcuts.md documentation inaccuracies

Major fixes:
- Toggle Sidebar was Cmd+B, actual shortcut is Opt+Cmd+Left (renamed to Toggle Left Panel)
- Toggle Right Panel was Cmd+\, actual shortcut is Opt+Cmd+Right
- Document Graph Tab cycling didn't exist in code, removed it
- Document Graph Enter key behavior was wrong: re-centers for docs, opens URL for external
- Keyboard Mastery levels were completely wrong (Novice/Apprentice/etc vs Beginner/Student/etc)
- Keyboard Mastery location was "status bar" but it's actually in Shortcuts Help panel

Added missing shortcuts:
- New Agent Wizard, New Group Chat, Navigate Back/Forward
- Toggle Input/Output Focus, Focus Left Panel, System Log Viewer, Process Monitor
- Toggle Bookmark, Maestro Symphony, Toggle Auto Run Expanded, View Git Diff
- Toggle Tab Star, Toggle Tab Unread, Filter Unread Tabs, Open Prompt Composer
- Go to Tab 1-9 and Go to Last Tab
- File Preview Go Back/Forward
- Context-sensitive filter shortcuts (Cmd+F in different contexts)
