Make rate-limit header parsing null-safe

Browse source 
Use ParseOrNull helpers for X-RateLimit-Remaining and X-RateLimit-Reset-After header values and make the TimeSpan conversion null-safe. This prevents exceptions when rate-limit headers are missing or malformed and keeps resetAfterDelay nullable while preserving existing rate-limit logic.
