feat(02-03): add TOTP setup/enable/disable, password reset, and frontend_url to config
- GET /api/auth/totp/setup: returns provisioning_uri + secret (400 if already enabled) - POST /api/auth/totp/enable: rate-limited 10/min, verifies TOTP code with Redis replay prevention, returns 10 backup codes - DELETE /api/auth/totp: disables TOTP, clears secret, deletes backup codes - POST /api/auth/password-reset: always returns 202 (anti-enumeration), enqueues Celery email task - POST /api/auth/password-reset/confirm: validates token, strength, HIBP; updates password; no auto-login (AUTH-05) - config.py: added frontend_url setting for password reset link construction - test_auth_totp.py: all 11 tests passing (GREEN)
