Adds the frontend half of the v0.3.0 desktop paid model. The Tauri
shell (in velxio-prod) emits velxio://license-required when the
license gate refuses to spawn the sidecar; this commit teaches the
OSS desktop overlay to react.
- LockoutOverlay.tsx (new): full-screen modal with three variants
(no_credential / tampered / expired). Sign-in or paste-key
resolves it via restartApp().
- DesktopWelcomePage.tsx: new grandfather variant - "you have N
days to keep using Velxio Desktop" + "Continue without signing in".
- GraceBanner.tsx: rewrite with pre-expiry tones (5d amber, 24h
red, dismissible), polling every 10 min while document visible,
separates pre/post-expiry messaging.
- Esp32QemuPrompt.tsx: signup gate for grandfather users (ESP32
binaries are not part of the grandfather grace) + inline progress
bar driven by velxio://esp32-qemu-progress events.
- index.ts: rewires on getGateInfo() at first paint to decide
welcome vs lockout vs nothing; installs license-required listener
+ 10-min foreground polling for the locked transition.
- tauriBridge.ts: adds GateInfo type, getGateInfo(), restartApp().

New `frontend/src/desktop/` module loaded only when VITE_DESKTOP=true.
Hosts the Tauri-bound UI that pure OSS doesn't need:
- tauriBridge.ts typed invoke / listen / openExternal / beginSignIn
wrappers with no-op fallbacks for `vite dev` outside
the Tauri webview.
- DesktopWelcomePage.tsx sign-in flow with browser handoff +
paste-key fallback; listens for
`velxio://auth-completed` from the shell.
- GraceBanner.tsx renders soft/hard grace banners driven by
`license_status` + `velxio://license-status`
emits from the background checkin loop.
Toggles `body.vlx-desktop-readonly` so the
editor's Save / Compile buttons disable
themselves via CSS in hard-grace.
- Esp32QemuPrompt.tsx one-time download modal when the user picks
an ESP32 board on a fresh install.
- index.ts mounts welcome conditionally and the side
panels unconditionally.
- desktop.css shared styles.
All entry points are no-ops outside Tauri so the existence of the
folder has zero effect on the OSS build.
