Feature 2373- move widgets to all locations

[EliorGigi]

Changes Made

1. Moved the following widgets from road_segment_widgets to all_location_widgets:

   • killed_and_injured_count_per_age_group
   • killed_and_injured_count_per_age_group_stacked
   • injured_count_by_severity

2. Fixed the /api/infographics-data endpoint's news_flash_id argument (reflects the update in the Swagger documentation).

3. Resolved a bug in the histogram within the killed_and_injured_count_per_age_group widget. Previously, when there were no accidents with the "unknown" type, the widgets crashed. This issue can be observed in the production logs. For instance, the following API call was successful:

   • https://www.anyway.co.il/api/infographics-data?lang=he&news_flash_id=154488&years_ago=5

   However, the same API call with a 3-year parameter instead of 5 resulted in a crash:

   • https://www.anyway.co.il/api/infographics-data?lang=he&news_flash_id=154488&years_ago=3

   The issue arises when there are no accidents with an "unknown" type within the last 3 years, as all the accident ages are known during that period.
