refactor(playground): remove playgroundMaxTokens helper and update input handling

- Deleted the `playgroundMaxTokens` helper functions and their associated tests.
- Updated `loadConfig` and `usePlaygroundState` to handle `max_tokens` directly without sanitization.
- Simplified input handling in `usePlaygroundState` to directly set values without normalization.
