[frontend] Align knowledge bar counters (#8115)

[delemaf]

Proposed changes

• Fix distribution counters, also add counter for related entities
• Refactor query with fragment for knowledge bar
• NB: counters update is still not sync when entity is added (it's another bug 🐛 )

Related issues

• Close Incorrect display in Threat Actors menu category
• Close In an Incident, the Observables count on Knowledge is one below the actual count

Checklist

• I consider the submitted work as finished
• I tested the code for its functionality
• I wrote test cases for the relevant uses case (coverage and e2e)
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality
