[frontend] fix limit results to display correlation view (#5996)

[frapuks]

Proposed changes

• Increase the limit to 500 (default: 20) for results sent by the backend, to display a graph consistent with overview / correlated reports

Related issues

• Report->Knowledge->Correlation view missing data and inconsistent #5996

Checklist

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

Further comments

This will retrieve all the observables linked to the report, up to a limit of 500.
To get around the 500 limit, in the case of a report with more relationships, you would have to completely rethink the method for retrieving this data.

Test procedure

• Use demo data (yarn insert:dev)
• Create new report
• In Knowledge, add 'send.have8000.com' indicator
• Click on 'correlation view' => The graph display a relation between your NewReport and 'Poison Ivy' report
• Go to 'Poison Ivy' report / overview / Correlated report => Expected : display line with your NewReport
• Go to Knowledge / Correlation view
• => [branch master] Nothing ! Expected : minimum the same relation
• => [branch issue/5996] a beautiful graph with all relations
