Investigate removing "api" prefix from API routes

[Jack-Edwards]

API routes are currently prefixed with "api". This was intended to support hosting the web client and web API from the same host, using the same reverse-proxy.

Do API endpoints need to be prefixed with "api"? Probably not.

Investigate using Caddy's strip_prefix function to eliminate this requirement.

Example API path where "api" could be removed:

Crypter/Crypter.API/Controllers/AccountRecoveryController.cs

Line 45 in f1ab20c

[Route("api/user/recovery")]
