feat(console): embed the management UI in release binaries

- build locked Web dependencies automatically for release profiles
- keep debug Cargo builds independent from the Vite development server
- embed generated Host, Page, manifest, and service worker assets
- serve exact control-plane assets with MIME and cache headers
- reject non-canonical and unknown paths without an SPA fallback
- cover embedded document boundaries and path validation
