perf(observer): increase socket and request timeouts to 10 seconds

- Keep gateway assessment concurrency at 10 (reverting previous change)
- Increase socket timeout from 5s to 10s for better stability
- Increase all request timeouts from 5s to 10s to match socket timeout
- Maintain serialized ownership checks for better load distribution

This gives slow gateways more time to respond while keeping high concurrency
for better throughput across the network.
