Software indicator: reduce number of API calls

The useSoftwareIndicator hook requests its data in several API calls. For example, it loads the dimensions, attributes and levels in three different requests.

We could try to reduce the number of requests by combining the different endpoints into one. Here are some ideas:

• The dimensions, attributes and levels could be loaded from a single endpoint /get_software_indicator_data (possibly a better name) that would take the evaluation year as a parameter. The data could be returned nested or flat:
  • Nested:

    type Level = {
      id: number
      level: number
      description: string
    }
    
    type Attribute = {
      id: number
      name: string
      weight: number
      levels: Level[] // or Record<number, Level>
    }
    
    type Dimension = {
      id: number
      name: string
      year: string
      description: string
      attributes: Attribute[] // or Record<number, Attribute>
    }
    
    type SoftwareIndicatorData = Dimension[] // or Record<number, Dimension>

  • Flat:

    type Level = {
      id: number
      level: number
      description: string
      attribute: number
    }
    
    type Attribute = {
      id: number
      name: string
      weight: number
      dimension: number
    }
    
    type Dimension = {
      id: number
      name: string
      year: string
      description: string
    }
    
    type SoftwareIndicatorData = {
      dimensions: Dimension[] // or Record<...>
      attributes: Attribute[] // or Record<...>
      levels: Level[] // or Record<...>
    }

• The dimension and attributes scores could be loaded in the same request. The calculation of the dimension score already includes the calculation of the attribute scores, so this would also avoid doing the same calculation twice.
