feat(host): unified host + native pairing over the management API

`serve --native` now runs the GameStream host AND the native punktfunk/1 (QUIC)
host in ONE process, sharing a single NativePairing handle with the management API
— so native pairing is operable from the web console instead of journalctl.

- gamestream::serve gains a native_port: spawns crate::m3::serve in the same
  runtime and passes the shared NativePairing to mgmt::run. Validated live: one
  process binds both RTSP 48010 and QUIC 9777.
- mgmt API: new `native` endpoints — GET /native/pair (status), POST
  /native/pair/arm (mint a fresh, time-limited PIN to DISPLAY), DELETE /native/pair
  (disarm), GET/DELETE /native/clients (list/unpair). GameStream-only hosts report
  enabled:false. OpenAPI regenerated (checked-in doc + drift test).
- main.rs: serve --native / --native-port flags.

The native host arms pairing on demand (the operator reads the PIN from the
console; the SPAKE2 ceremony is host-shows-PIN). New mgmt + native_pairing tests.
