refactor: update API with DexParamEnum and simplify TradeConfig

- Introduce DexParamEnum to replace Dex enum for protocol parameters
- Simplify TradeConfig::new() to accept only 3 essential parameters
- Update all examples to use new DexParamEnum API
- Optimize executor and params modules
- Remove deprecated wsol_use_seed and mint_use_seed parameters
- Fix fast_fn module exports
