Gradually replace custom API caching with react-query

[jordyvandomselaar]

At the moment, the front-end's API calls use a custom caching layer. We can make this significantly simpler by using something like react-query to handle the caching for us.

This will also make it easier to run API calls concurrently by default by making concurrency an opt-out experience rather than opt-in

We are currently replacing API calls with react-query incrementally. Conversion list:

• [x] blocking/blocked by
• [x] lists
• [x] handle history
• [x] homepage stats
• [ ] account/handle resolution useResolveAccount
• [ ] post history & embeds
