test: Achieve 100% test coverage\! 🚀

Add comprehensive tests for previously uncovered wrapper methods:

EVM Wrapper methods tested:
- transfers() - EVM token transfer events
- swaps() - Basic DEX swap transactions
- swaps_advanced() - Advanced swap filtering with all parameters
- pools() - DEX liquidity pool data
- price_history() - OHLC price data for tokens
- pool_history() - OHLC data for DEX pools
- token_holders() - Token holder balances by contract

SVM Wrapper methods tested:
- transfers() - Solana SPL token transfers with full parameter coverage

Coverage Results:
- Total statements: 1,018
- Statements covered: 1,018
- Missing statements: 0
- Test coverage: 100.00% (up from 98.43%)
- Total tests: 231 (up from 215)

All tests pass with zero linting errors and perfect code coverage.
