Captcha silently bypassed when RECAPTCHA_SECRET is missing — no NODE_ENV guard

[nanaf6203-bit]

File: src/auth/auth.service.ts (verifyCaptcha)

Returns true and logs a warning when the secret isn't configured. NODE_ENV is not checked.

Impact: A misconfigured production deploy effectively disables bot protection on /auth/login.

Fix: Only bypass when process.env.NODE_ENV !== 'production'. Throw otherwise.
