Inspections can be very long

[pvgennip]

If I am logged in as pim@iconize.nl, I get 3170 inspections:

I think we should paginate /inspections and /alerts to about 100 per page. And add lazy loading if you scroll down further.

Building up the /diary screen takes about 5 seconds, after the data has been loaded.
