feat: Separate cache expiry for stats and search

Browse source 
Allows us to set different cache eviction timespans  for search queries
and statistics.

Stats and especially "last package updates" should probably be refreshed
more often, whereas we might want to cache search results for a bit
longer.

So this gives us a bit more flexibility playing around with different
settings and tweak things.
