Hwang 336d637b72 feat(param-search): Add new evaluation functions for breakout, momentum, and tail parameter combinations
Changes:
- Added `apply_params_to_db` function to streamline parameter application to the database.
- Introduced `evaluate_breakout_param_combo`, `evaluate_momentum_param_combo`, and `evaluate_tail_param_combo` functions to enhance the evaluation of parameter combinations for respective strategies.
- Updated `requirements.txt` to include `optuna==4.2.1` for improved optimization capabilities.

Impact:
- These additions improve the modularity and efficiency of parameter evaluations across different trading strategies, facilitating better optimization and backtesting processes.
