Make relay opt-in when pairing devices (#2706)

* feat: make relay opt-in for device pairing

* fix(relay): keep pairing state authoritative

* fix(relay): refresh pairing state across transports

* fix(onboard): honor explicit relay opt-out

* fix(relay): surface transport startup failures

* fix(pairing): gate offers for older daemons

* test(cli): rely on real pairing transport coverage

* fix(cli): report live relay without a pid file

* fix(relay): synchronize config during daemon startup

* fix(relay): preserve mutability for ignored overrides

* fix(cli): use reachable daemon for pairing

* fix(app): redirect invalid pair device routes

* fix(pairing): support remote host device pairing

Keep Pair Device host-relative through the existing settings and daemon RPC flow. Route CLI output through an injected adapter so workflow tests do not mutate process globals.

* fix(pairing): validate pairing destinations

Expose the host-relative Pair Device flow on every supported app platform. Reject a reachable daemon whose identity does not match the requested Paseo home before reading or mutating its pairing state.

* fix(pairing): render QR codes across platforms

Generate SVG text without DOM or canvas and render it through the existing cross-platform SVG stack.

* fix(cli): pair from persisted relay state

Allow explicit relay pairing while the daemon is stopped when relay is already enabled in persisted configuration.
