Migrate to a better GraphQL query for usage

[ryanw-mobile]

From official Octopus GraphQL usage:

query getMeasurements($accountNumber: String!, $first: Int!, $utilityFilters: [UtilityFiltersInput!], $startOn: Date, $endOn: Date, $startAt: DateTime, $endAt: DateTime, $timezone: String, $cursor: String) {
  account(accountNumber: $accountNumber) {
    properties {
      id
      measurements(
        first: $first
        utilityFilters: $utilityFilters
        startOn: $startOn
        endOn: $endOn
        startAt: $startAt
        endAt: $endAt
        timezone: $timezone
        after: $cursor
      ) {
        edges {
          node {
            value
            unit
            ... on IntervalMeasurementType {
              startAt
              endAt
              __typename
            }
            metaData {
              statistics {
                costInclTax {
                  costCurrency
                  estimatedAmount
                  __typename
                }
                value
                description
                label
                type
                __typename
              }
              __typename
            }
            __typename
          }
          __typename
        }
        pageInfo {
          hasNextPage
          hasPreviousPage
          startCursor
          endCursor
          __typename
        }
        __typename
      }
      __typename
    }
    __typename
  }
}

Variables:

accountNumber: "A-******"
endAt: "2024-10-19T22:59:59.999Z"
first: 60
startAt: "2024-10-18T23:00:00.000Z"
timezone: "Europe/London"
utilityFilters: 
{
electricityFilters: {
deviceId: "******"
marketSupplyPointId: "*****"
readingDirection: "CONSUMPTION"
readingFrequencyType: "HOUR_INTERVAL"
}

The returned value contains the parsed standing charge and consumption cost,
so we don't have to fetch and parse the raw readings and lookup tariffs.

Progress and to-dos on 9 Feb 2024:

• Migrated to GraphQL and matched the domain model structure - that means the data presented should remain the same.
• UserProfile is passed from Usage Screen to use case as preferences do not currently store device Id for the selected meter.
• local cache currently keep indexing data using meter serial, but we have to migrate to use device id and retire meter serial. (so DB schema has to be upgraded)
• Domain model has to be modified to add data fields to keep the cost for that consumption - so that we can then remove the cost lookup in viewmodel/usecase.
