David Bruno Vontor f4c4a8bfd1 Sanitize envs, optimize Dockerfile, Turnstile
Redact sensitive AWS keys in backend/.env.example and add VITE_TURNSTILE_SITE_KEY and VITE_USE_TURNSTILE to frontend/.env.example. Optimize backend Dockerfile by installing Python requirements immediately after copying requirements.txt (enables Docker cache) and remove the duplicate later install. Update turnstile verification to skip checks when USE_SSL is disabled (dev/non-HTTPS) and keep the existing no-secret bypass; add debug logging for the SSL bypass.
