Reorganize and consolidate HTTP routes.

HTTP routes are now defined in a single, unified module, pulling them out of the topical modules they were formerly part of.

This is intended to improve the navigability of the codebase. Previously, finding the handler corresponding to a specific endpoint required prior familiarity, though in practice you could usually guess from topic area. Now, all routes are defined in `crate::routes`.

Other than changing visibility, I've avoided making changes to the handlers at the ends of those routes.
