refactor(gas-fee): Refactor Gas Fee Strategy API

- Rename add_* methods to set_* for clarity
- Simplify normal strategy API (remove TradeType param)
- Expose set/del methods for flexible strategy management
- Update docs and examples to match new API

BREAKING CHANGE: Method names changed for Gas Fee Strategy
