Auth hardening: login rate-limiting + session fixation defenses

- login.php: Redis-backed per-IP rate limit (10 fails / 15 min lockout), keyed off CF-Connecting-IP/X-Forwarded-For so it sees the real client behind NPM; fails open if Redis is down

- login.php: session_regenerate_id(true) on successful auth (prevents session fixation)

- php.ini: session.use_strict_mode = 1 (reject unknown/attacker-supplied session IDs)

- netscan.php: constant-time hash_equals for the registration-key check (matches agent.php)

Cookie flags already HttpOnly + SameSite=Lax (verified live). Agent auth verified: missing/bad X-Agent-Key -> 401 on every machine action.
