adlee-was-taken f1ae5841bc fix(ext): generate_device_keypair returns object not JSON string ...

The wasm-bindgen binding for generate_device_keypair uses
serde-wasm-bindgen and returns a plain JsValue (object), not a JSON
string. Two consumers were calling JSON.parse on it, causing the
runtime error 'SyntaxError: "[object Object]" is not valid JSON' which
broke device registration end-to-end.

Fixes:
- wasm.d.ts: return type now { public_key_hex; private_key_base64 }
  matching the rate_passphrase pattern (also a JsValue-returning
  binding).
- popup-only.ts (register_this_device handler) and setup.ts (initial
  device wire-up): drop JSON.parse, use the object directly.
- router.test.ts: pin the contract — mock generate_device_keypair as a
  function returning an object (matching real binding behavior) and
  assert register_this_device returns ok and forwards the public key.
