Phase 0: Fix AppSidebar useEffect for module settings loading

- Updated AppSidebar to filter out disabled modules from navigation
- Added ModuleGuard to all module routes (planner, writer, thinker, automation)
- Modules now dynamically appear/disappear based on enable settings
- Routes are protected and redirect to settings if module is disabled
