refactor: simplify GasFeeStrategy from singleton to static methods

- Replace OnceLock singleton pattern with LazyLock static storage
- Convert instance methods to static methods for better performance
- Remove enabled/disabled strategy type management complexity
- Update parallel execution to use new static API
