so pure report generation (Overview) of ca. 5.000 rules via API only takes 2 seconds
[x] maybe we can re-add timing data to the log in debug mode during report generation again (time the different generation steps take)
[x] rule numbering does not work anymore or rulesets with header lines (broken by performance improvement --> @NilsPur )
[x] is there a hard memory limit of 4 GB for the middleware server?
[x] need to generate a new JWT after the initial long API call to be safe
[x] need to improve perfomance for the API call!
[ ] need to find out why there is a 5s delay between the API network packets
[x] need to improve error catching in MW server so it won't just stop
[ ] need to improve logging in UI server as it does not show any entry while logging in when MW server is dead (just the browser shows "> is an unexpected token")
[ ] API might crash with big scheduled reports (30.000 rules)
