Declare proprietary licensing and enforce permissive-only dependencies

Continuum is intended to be sold, so every dependency has to permit
distribution in closed-source commercial software. Our own crate and npm
packages carried no licence field, which made `cargo deny` report the
Tauri crate as `unlicensed`.

The Nuxt/Tauri dependency graph audited clean (MIT/Apache/ISC/BSD, plus
BlueOak-1.0.0 - which is why this allow list carries BlueOak where
continuum-cad's did not). Two entries worth knowing, both recorded in
continuum-common's docs/LICENSES.md: `node-forge` is
`(BSD-3-Clause OR GPL-2.0)` and we elect BSD-3-Clause, and
`caniuse-lite` is CC-BY-4.0 build-time data that is not bundled into the
built SPA, so no attribution obligation today.
