feat: Implement Alpha list and metrics enhancements

- Added new metrics fields: sub_universe_sharpe, robust_universe_sharpe, two_year_sharpe, prod_correlation, pnl, check_type, and neutralization to the Alpha model. - Updated snapshot_columns function to derive new metrics and check types from platform snapshots. - Enhanced API to include failed checks and check types in responses. - Created migration script to backfill existing Alpha records with new metrics and check types. - Updated frontend components to display new metrics and allow editing of custom tags. - Improved filtering and sorting capabilities for new metrics in the Alpha list. - Added tests for new functionality including checks classification and metrics filtering.
