Replace custom register token with spatie/laravel-honeypot

Swap the custom 'rt' register token anti-spam mechanism for
spatie/laravel-honeypot on the registration and parental-controls
invite flows.

- Add spatie/laravel-honeypot and publish config/honeypot.php
- Remove getRegisterToken() and the rt validation rule from RegisterController
- Replace the rt hidden field with the @honeypot directive in both forms
- Attach ProtectAgainstSpam middleware to POST /register and the
  parental-controls invite register route
- Update RegisterTest to disable honeypot for the valid registration case
