[susilnem]

Addresses

• Country pages - Context and Structure - FDRS data incorrectly displayed go-web-app#1396
• Fetch latest available data from FDRS #2285

Changes

• KPI_noLocalUnits changed to KPI_noBranches
• Updated the cron job databank -> FDRS
  This pull request's related to databank/management/commands/sources/FDRS.py.
• Change the field name in fdrs and worldbank related fields.
• Add new migrations file.

Need to run these commands.

python manage.py ingest_databank and python manage.py ingest_worldbank

Improvements to data fetching and processing:

• Changed the key from KPI_noLocalUnits to KPI_noBranches.

• Updated the prefetch function to fetch the latest data for each indicator by using the max function to get the entry with the highest year. (databank/management/commands/sources/FDRS.py)

• Modified the load function to ensure only the latest year's available data is used by checking the year before setting the value. (databank/management/commands/sources/FDRS.py)

@szabozoltan69
we also need to run these commands:
python manage.py ingest_databank and python manage.py ingest_worldbank

[szabozoltan69]

Both were run fine (ingest_databank had a slight issue).
