Refactor App.tsx into modular layout components

[jamby77]

Summary

• Extracted inline components from App.tsx into src/components/layout/: AppLayout, AppSidebar, NavItem, CommunityBanner, FeedbackModal
• Added shadcn UI primitives: Sidebar, Sheet, Input, and use-mobile hook
• Wrapped layout with SidebarProvider for shadcn sidebar support

Test plan

• Verify sidebar renders correctly with all nav items
• Verify locked features still show tooltip and redirect to settings
• Verify CLI toggle, feedback modal, and community banner work as before
• Verify print styles still hide sidebar
• Run pnpm build — passes clean

Note

Medium Risk
Touches licensing/entitlement and introduces a new registration email flow plus runtime license activation/persistence, which can impact access control and onboarding if misconfigured. Also adds CORS/env changes and substantial UI layout refactoring that could affect navigation and CLI panel behavior.

Overview
UI layout refactor: Extracts the large inline layout from App.tsx into modular components (AppLayout, AppSidebar, NavItem, FeedbackModal) and switches to new shadcn primitives (Sidebar, Sheet, Input, useIsMobile) for a responsive, collapsible sidebar and updated CLI panel positioning/print hiding.

Early-access licensing UX: Adds a new Settings → License section that lets Community users request a free license key via VITE_REGISTRATION_URL and activate a key via a new POST /license/activate, with immediate license-status refresh; locked nav items now route to Settings with a “Register free” tooltip/badge, and webhook upgrade copy is updated accordingly.

Backend licensing/registration: Adds a v1/registrations endpoint in the entitlement service that creates/reuses a customer and issues (or re-sends) an Enterprise license key via a new Resend-based EmailService; entitlement validation now supports cloud tenant resolution via tenantId, and the licenses service gains runtime activation with safe state handling, disk persistence of the key, and more robust error propagation/parsing (with new tests).

btw, do we need the CLI entry in the sidebar as well, when we have it at the bottom of the screen? It can free some ui space if we remove it from the sidebar
