Update homepage tiles

We currently have a number of tiles on the homepage that are unnecessary or unlinked. They should be properly linked to their respective targets or removed if not needed. This includes:

- 6 homepage tites
- ~8 product icon / tiles

Start by locating the homepage implementation and inventorying the six homepage tiles and approximately eight product icon tiles named in the issue. Check each tile's target and determine which are unnecessary; done means every retained tile links to its intended target and unwanted tiles are removed.
