Fix compression threshold max limit from 4000 to 8000

- Updated hardcoded max limit in CompressThreshold input to match the 8000 token configuration
- Resolves issue where UI was limiting users to 4000 tokens despite backend supporting 8000
- Now allows users to set compression thresholds up to the full 8000 token limit
