fix(desktop): repair fullscreen window controls

[murongg]

Summary

• Route the desktop View > Enter Full Screen menu command through Markra's frontend fullscreen handler on non-macOS platforms.
• Preserve macOS's native fullscreen menu role so menu-bar fullscreen stays system-managed.
• Make the self-drawn green traffic-light button toggle true fullscreen instead of only maximizing to the desktop viewport.
• Minimize through a native desktop command; on macOS it exits system fullscreen first, then miniaturizes the window after the fullscreen transition starts.
• Keep the app test harness Tauri mock in sync with the fullscreen export used by App tests.

Why

• Fixes the Windows 11 menu fullscreen no-op reported in [Bug]: 全屏功能无效 #258.
• Avoids regressing macOS native fullscreen behavior when entering fullscreen from the menu.
• Keeps self-drawn macOS traffic-light controls aligned with native behavior for fullscreen and minimize-from-fullscreen.

Validation

• pnpm exec vitest run src/components/MacWindowControls.test.tsx passed
• pnpm exec vitest run src/runtime/tauri/window.test.ts passed
• cargo fmt --manifest-path apps/desktop/src-tauri/Cargo.toml --check passed
• cargo test --manifest-path apps/desktop/src-tauri/Cargo.toml --locked passed
• pnpm test passed
• pnpm run typecheck:test passed
• pnpm build passed

Risk

• Manual packaged Windows/macOS app QA is not included in this branch; behavior is covered by focused tests, local build, and GitHub Actions.

Closes #258
