feat: MaaS registry management + events page + workspace consolidation

- Add MaaS provider registry (4 new Tauri commands: get/save/upsert/delete)
- New /settings/maas page with MaasRegistryView for managing model providers
- New /events page
- Extract LLM provider presets to constants (LLM_PROVIDER_PRESETS)
- Consolidate Home view into WorkspaceView (remove standalone Home)
