Fix #34: E-Mail-Versand via PHP

- PHP POST handler with server-side validation (name, email, message)

- Recipient: mki@kies-media.de
- Honeypot spam protection (hidden field)
- Minimum submit time check (3 seconds)
- Session-based rate limiting (60s between submissions)
- Header injection protection
- Error messages displayed above form
- Success message after successful send
- Form values preserved on validation errors
