Wrong decryption key JSON format

[ylembachar]

The decryption key in the JSON response is not well-formed when queried from the Keyper - this is different than the format returned by the API when the key is found in the DB:

{
  "message": {
    "decryption_key": "\"0x8af9ccecbd16c2560d685d8c8de9114610dea7ae29e820b6b622de1201cef2048b92f204f3494ba7f9fdb2e8254f4c93\"\n",
    "identity": "0xf84f5007dbe39b980f43de828c40b85b8608ffe2f500e4fb5de9a1b0dfbfd2cf",
    "decryption_timestamp": 1765411200
  }
}
