/**
 * Lists Safe transactions with optional filtering by Safe and status.
 *
 * Migration: Phase 4 - Tier 2 command
 * - Old: 177 lines of imperative console.log with complex filtering logic
 * - New: Declarative Ink rendering
 *
 * Benefits:
 * - Clean separation: selection (prompts) → display (Ink)
 * - Reusable TransactionListScreen component
 * - Automatic sorting and summary statistics
 * - Consistent styling and formatting
 * - Much cleaner code (~177 → ~80 lines = 55% reduction)
