Create a stable and reviewed version of signed message

Concept

Currently, there are two version of signed messages created from Capture App.

Pre 0.34.2 example:

{
  "indexedAssets":{
    "<the-file-content-encoded-as-base64>":{
      "mimeType":"video/mp4"
    }
  },
  "truth":{
    "providers":{
      "CapacitorFactsProvider":{
        "APP_BUILD":"152",
        "APP_ID":"io.numbersprotocol.capturelite",
        "APP_NAME":"Capture",
        "APP_VERSION":"0.32.2",
        "BATTERY_LEVEL":0.9599999785423279,
        "DEVICE_NAME":"EXODUS 1",
        "DISK_FREE":412057600,
        "DISK_TOTAL":4225581056,
        "GEOLOCATION_LATITUDE":25.005851,
        "GEOLOCATION_LONGITUDE":121.4586974,
        "IS_CHARGING":true,
        "IS_VIRTUAL":false,
        "MANUFACTURER":"HTC",
        "MEM_USED":5414752,
        "OPERATING_SYSTEM":"android",
        "OS_VERSION":"9",
        "PLATFORM":"android",
        "UUID":"16eb24e0fa1f8a28"
      }
    },
    "timestamp":1625213302097
  }
}

0.34.2 or later example:

{
  "indexedAssets":{
    "47af037408a25364f8d18b133fa96ba4afb2b60e53d5329ee629e2a28a8e2bcd":{
      "mimeType":"video/mp4"
    }
  },
  "truth":{
    "providers":{
      "CapacitorFactsProvider":{
        "APP_BUILD":"152",
        "APP_ID":"io.numbersprotocol.capturelite",
        "APP_NAME":"Capture",
        "APP_VERSION":"0.32.2",
        "BATTERY_LEVEL":0.9599999785423279,
        "DEVICE_NAME":"EXODUS 1",
        "DISK_FREE":412057600,
        "DISK_TOTAL":4225581056,
        "GEOLOCATION_LATITUDE":25.005851,
        "GEOLOCATION_LONGITUDE":121.4586974,
        "IS_CHARGING":true,
        "IS_VIRTUAL":false,
        "MANUFACTURER":"HTC",
        "MEM_USED":5414752,
        "OPERATING_SYSTEM":"android",
        "OS_VERSION":"9",
        "PLATFORM":"android",
        "UUID":"16eb24e0fa1f8a28"
      }
    },
    "timestamp":1625213302097
  }
}

Reason/Hypothesis

Signature is not something that we'd like to see it changes from time to time. We should make sure the current signature contains all the information we want, and make it stable and lasting.
