feat: refactor seed optimization to global configuration in v3.2.0

- Remove open_seed_optimize parameter from TradeBuyParams and TradeSellParams structs
- Add global use_seed_optimize configuration in TradeConfig with default value true
- Add create_wsol_ata_on_startup configuration in TradeConfig with default value true
- Implement automatic WSOL ATA creation and verification on SDK initialization
- Add with_wsol_ata_config() builder method to TradeConfig for custom WSOL settings
- Update all examples to remove open_seed_optimize parameter usage
- Update documentation (README, TRADING_PARAMETERS) to reflect new configuration approach
- Upgrade package version from 3.1.7 to 3.2.0

Breaking Changes:
- open_seed_optimize parameter removed from trade parameters (now global setting)
- Seed optimization is now enabled by default for all operations
