Subject: Remove defunct CAPTCHA

The hCaptcha integration has been abandoned for a while. It added yet
another questionable third-party API (which also set a Cloudflare
cookie), and its effectiveness is unclear considering its client-side
nature.

A custom CAPTCHA implementation (such as PoW challenge) is an
interesting prospect, but it'll require proper server-side support.
