feat(python): generate the Python wrapper with UniFFI instead of pyo3

Build the Python bindings from the existing devolutions-crypto-uniffi
scaffolding via maturin (bindings = "uniffi") rather than a hand-written pyo3
wrapper. Still imported as `devolutions_crypto`.

- Drop the pyo3 crate and the hand-written .pyi stub; the python/ crate now
  only hosts the uniffi-bindgen binary maturin invokes
- Gate that binary's uniffi CLI dependency to non-wasm targets so wasm builds
  (wasm-pack over the workspace) are unaffected
- Build a single py3-none wheel per target in CI (UniFFI bindings are
  ABI-independent, so the per-Python-version matrix is no longer needed)
- Port the Python test suite to the UniFFI API and add derive_encrypt tests
  mirroring the other wrappers
- Update the PyPI usage examples for the UniFFI API

This is a breaking API change for Python consumers (shapes follow UniFFI);
the wrapper is used only for testing.
