155 - No category "ServiceNow Research" in homepage and sidebar + Optimise index

[andreituicu]

The lighthouse score for the homepage and blog list pages had been declining since we've been importing more blog pages, as the size of the payload being transferred over the network had increased. This PR optimises the access to the index by transferring one chunk at a time, only when needed, instead of bringing all the entries in 1 go.

Additionally: Fix #155
