fix(transaction-filler): create dynamic mock trace for realistic price feed detection

- Fix mock trace implementation to detect accountLiquidity transactions (0xa824bf67)
- Simulate realistic nested calls to Pyth contract with multiple price feeds
- Remove request method from mock client to use fallback trace logic
- Now correctly detects 3 price feeds instead of 0 in example
