refactor: unify transaction building and execution architecture

- Remove redundant transaction builder functions and merge into single build_transaction()
- Simplify compute budget manager with unified add_compute_budget_instructions()
- Consolidate trade executor interface by removing separate buy/sell methods
- Unify BuyParams/SellParams usage, remove *WithTipParams structs
- Streamline parallel execution logic and remove TradeType parameter
- Delete obsolete files: address_lookup.rs, tip_cache.rs
- Clean up nonce manager by removing unused is_using_nonce() function

This refactoring reduces code duplication and provides a cleaner, more maintainable API
for transaction building and execution across all trading protocols.
