all users page broken, no sort, and no pagination

[tj-mai]

problems:

• sort does not work (missing ranks fe: 2,3,5)
• missing pages, sometimes there are only 121 users, another time it's 1000

acceptance criteria:

• if searchbox is not used: get all users from memory cache
• if searchbox IS used: only show the first 100 from meilisearch, do not show the pagination
  -- show information on the end: we're only showing the first 100, for more/other results, refine search
